Siege is a benchmarking that is configurable testing tool for websites that tests web servers by making requests for web pages. The number of pages per second that Siege requests can be set to anything from a few pages per second to the number that is maximum the internet site are designed for.
This info is excessively ideal for discovering performance bottlenecks by highlighting which host resource is exhausted very first as well as which traffic degree. Armed using this information, you could make modifications on host’s setup or update the host’s equipment before a site that is live. Additionally, typical system management procedures, such as for instance backups, could be tested under a simulated load to ascertain their influence on internet site performance.
In this guide, we are going to install and configure Siege to perform in benchmarking and browsing modes. The mode that is benchmarking as numerous demands due to the fact internet host are designed for, plus the browsing mode simulates a configurable amount of people to the internet site.
Because configuring a web connection that operates through a roxy ip address server is very easy with Firefox, we are going to utilize it in order to connect on Web through the Sproxy roxy ip address server. Sproxy, that has been particularly designed to make use of Siege, records the Address of each demand that passes through it to a file. We shall make use of that file to to share with Siege which URLs to try against.
In the part that is first of tutorial, we will install Sproxy and configure Firefox to connect to the Internet through it. From there, we shall produce a listing of URLs to own Siege test against, and, finally, we are going to examine the test outcomes and recognize performance bottlenecks.
Warning: just utilize Siege to try web sites which you either very own or have authorization to try. Utilizing Siege against unauthorized web sites could be considered a crime in certain nations.
In purchase to accomplish this guide, you will require:
- One Ubuntu 16.04 host create by third Ubuntu 16.04 initial host setup guide, including a sudo non-root individual and a firewall. Make sure to port that is open***************)8080 in Step 7 of the initial server setup tutorial with the command
sudo ufw allow 8080. This is the port that listens that are sproxy automagically.
- Firefox set up. You should download the installation file from the official Mozilla website if you are using macOS or Windows on your local computer. You should use your package manager or follow Mozilla’s official instructions to install Firefox if you are using Linux. This guide includes directions for dealing with Firefox variation 56.
- A internet site you possess or have authorization to try which either publicly available or you install Siege on.( that you can make accessible from the server*****************)
Step 1 — Building and Installing Sproxy
Sproxy just isn’t available as a pre-packaged binary, from its official website and then build it from source so you will have to download it.
Because Sproxy’s create procedure utilizes tools that aren’t set up on Ubuntu automagically, you will have to install some packages that are additional
First, improve your package list to ensure that you have the latest form of each extra package.
Then, install the packages.
- sudo apt-get install libnet-ssleay-perl liburi-perl libwww-perl that is build-essential
build-essential provides basic libraries and tools which are needed to build pc software on Debian-based Linux distributions, while
libwww-perl are libraries the Perl program writing language that Sproxy varies according to to create connections over SSL, manipulate URI strings, and user interface with all the global Web.
Now, modification to your residence directory and down load the source that is sproxy archive from the formal internet site.
- cd ~
- curl -O http://download.joedog.org/sproxy/sproxy-latest.tar.gz
Then, create a directory called
sproxy to construct Sproxy in and unpack the origin rule archive in to the directory that is new
- mkdir sproxy
- tar -zxf sproxy-latest.tar.gz --strip-components=1 --directory="sproxy"
right here, the
-zxf choice informs tar to
gunzip and draw out the articles regarding the
sproxy-latest.tar.gz file. The
--strip-components=1 choice strips 1st leading component from each file title. This unpacks the archive in to the
sproxy directory — specified by the
--directory choice — as opposed to into
Now, modification on
sproxy directory to construct and install Sproxy with all the
- cd sproxy
- sudo make install
./configure demand checks that regarding the program that is necessary and build tools are present on the system. The
make command then builds the scheduled system binaries. Finally, the
make install demand copies the binaries that are new their correct locations on the server. Because Sproxy creates a directory that is new
/usr/local/lib/sproxy/JoeDog, you will need to run
make install with root privileges.
Finally, test that Sproxy is working properly by heading back into the house directory to begin Sproxy in verbose mode with all the
The production lets you know the the slot that Sproxy is paying attention on, the positioning regarding the file that Sproxy is output that is writing, plus the amount of moments Sproxy will await an answer from a remote host.
Sproxy OutputSPROXY v1.02 paying attention on slot 9001 ...appending HTTP demands to: /user/urls.txt ...default connection timeout: 120 moments
If Sproxy doesn't begin, review the communications within terminal for details about just what went incorrect.
Once you have confirmed that every thing's working, stop Sproxy with
Sproxy is currently prepared to make use of, therefore let us alter Firefox in order to connect on Web through Sproxy to make a listing of URLs to benchmark with Siege.
Step 2 — Configuring Firefox to utilize Sproxy
We will now alter Firefox's networking setup to deliver all internet demands through Sproxy, producing record of benchmarking goals we are going to significance of Siege.
Because we wish Sproxy to record every URL we see, we are going to additionally clear Firefox's neighborhood internet cache. The internet cache is an area shop of pictures alongside content that is static websites that Firefox has already visited. By default, Firefox does not re-request assets that are website it has cached.
Modifying the System Settings
First, replace the Network Proxy settings beneath the General tab on Firefox's primary Preferences display.
- Open Firefox. (This guide includes directions for Firefox variation 56. For any other variations, see Firefox's formal help paperwork.)
- Click regarding the hamburger menu inside top, right-hand part regarding the display and choose Preferences to visit the General display.
- Scroll on base regarding the web page and find the Network Proxy part.
- Click regarding the Settings... key to start the Connection Settings panel.
In this panel, configure Firefox to pass through all its demands through server that is sproxy installed in action 1.
- Select Manual proxy setup.
- Enter your Sproxy host's general public internet protocol address inside HTTP Proxy industry.
- Set the slot quantity to
8080inside Port industry.
- Click OK to save lots of the modifications.
You have configured Firefox to utilize your Sproxy HTTP proxy ip server, so that you are quite ready to clear the cache that is local
Clearing the neighborhood Cache
Firefox describes the cache that is local Offline content. It's based in the Privacy and safety element of Firefox's Preferences display.
- Click regarding the hamburger menu inside top, right-hand part regarding the display and choose Preferences to visit the General display.
- Click Privacy & safety regarding the side that is left-hand of display.
- Scroll on base regarding the web page and find the Offline Web information and consumer Data part and press the Clear Now key.
Your internet cache is currently empty, and so the target of each HTTP-based asset that is website Firefox encounters will undoubtedly be passed away to Sproxy until that asset is re-cached.
Testing the Configuration
Firefox is currently configured to route all requests that are HTTP-based Sproxy, you stopped Sproxy with
CTRL+C at the conclusion of step one. therefore, you will notice one web page in the event that you make an effort to see an online site over an HTTP experience of Firefox now.
If you may not see this mistake message, verify that your particular Firefox settings match the screenshots that are previous double-check that you will be maybe not linking on internet site over HTTPS.
when you wish to utilize Firefox typically once again, re-trace the instructions that are previous Modifying the system Settings, but, this time around, choose the No proxy choice regarding the Connection Settings panel.
Now we can create a list of URLs by starting Sproxy and browsing the target website with Firefox.( that we have configured Firefox to connect to the Internet via Sproxy,*****)
Step 3 — beginning Sproxy and creating an Address List
In this, we are going to begin the server that is sproxy use Firefox to browse the target website. Sproxy will record every URL that is HTTP-based that demands to a file we use later on with Siege.
First, modification to your residence directory and commence Sproxy.
- cd ~
- sproxy -v -t 180 -p 8080 -o mixed-urls.txt your_server_ip
-vprints the URLs being required on terminal.
-tmay be the amount of moments that Sproxy will await a reply from a remote host.
-pmay be the slot that Sproxy will pay attention in.
-omay be the file that Sproxy will compose the URLs to.
your_server_ipmay be the internet protocol address that Sproxy will bind to.
The production straight away lets you know the form of Sproxy you're operating, the slot that Sproxy is paying attention on, the file that Sproxy is composing URLs to, plus the timeframe Sproxy will await a remote host to react. When you begin searching the test internet site, the production also are the URLs regarding the websites that Sproxy is recording.
Sproxy OutputSPROXY v1.02 paying attention on slot 8080 ...appending HTTP demands to: mixed-urls.txt ...default connection timeout: 180 moments http://www.example.com/ http://www.example.com/index.html http://www.example.com/about.html
Note: Sproxy doesn't help HTTPS connections, so that you must browse your test website via HTTP to be able to produce record of URLs. But Siege does help HTTPS, and, in action 5, we are going to explore changing the HTTP-only list that is URLs examine your internet site over both HTTP and HTTPS.
After you have got started Sproxy, come back to Firefox and commence searching the goal website. Sproxy shall compose every Address that Firefox demands on
mixed-urls.txt file while at the same time printing the URLs on terminal.
Once you have got checked out the websites you want to try, stop Sproxy with
You will have an inventory inside
mixed-urls.txt file of each URL that is HTTP-based that encountered on the test website. The step that is next to get rid of any URLs which do not resolve to your site to ensure that you merely make use of Siege against authorized domain names.
Step 4 — Sanitizing the URLs File
Modern web sites content that is often host more than one location. This content may be images hosted on a delivery that is content (CDN) or fonts hosted on a third-party solution like Google. We want to ensure that we are only benchmarking domains that we have permission to test when we run Siege. Therefore, any URLs must be removed by us inside
mixed-urls.txt file which do not indicate the goal internet site.
Use grep, a software application for looking text that is plain against user-specified regular expressions, to locate just those URLs that match your test domain and redirect the outcomes to a fresh file called
- grep -a "^http://www.example.com" mixed-urls.txt > urls.txt
-a banner informs grep to deal with a binary file like a text file. This is certainly necessary because browsers often make PUBLISH demands containing binary information, which Sproxy would then compose to
mixed-urls.txt. If you have data that are binary
mixed-urls.txt, grep would fail minus the
In regular phrase terms, the
^ character suggests that strings must focus on
http://www.example.com become considered a match.
This demand will create no production inside terminal, nonetheless it will generate a file that is new
urls.txt to ensure every line starts along with your test web site's domain title and delete any lines which do not.
Save your modifications and shut the file while done modifying.
Your URLs list now contains just those URLs so we are ready to install Siege that you have permission to test. If you would also like to benchmark your website via HTTPS, follow the optional instructions in Step 5 to create a URL that is second file contains HTTPS variations of the URLs.
Step 5 — producing an HTTPS Address File (Optional)
Many web sites stepped on both HTTP and HTTPS as well as over HTTPS solely, that you can benchmark your website over HTTPS, too so it is important. This is certainly one thing Siege may do. You merely must offer it a listing of URLs that focus on
First, make use of the
cat demand to start
urls.txt and pass its articles to sed, a software application for parsing and text that is transforming. Sed will replace all instances of
https and display the total leads to the terminal.
- cat urls.txt | sed 's|http|https|'
The production could be the list that is same of you have inside
urls.txt file, except that all regarding the outputted URLs begins with
Example Outputhttps://www.example.com/ https://www.example.com/index.html https://www.example.com/about.html
Once you have got confirmed the production, re-run the demand, this time around composing the production to a fresh file called
- cat urls.txt | sed 's|http|https|' > urls-https.txt
This demand wont create any production on terminal, because it has all been rerouted into
Now we are ready to install Siege and begin testing.( that we have the updated URLs list,*****)
Step 6 — Benchmarking and Testing with Siege
(you must first install Siege.
Before you can begin testing your website,*****)
Siege can be acquired from Ubuntu that is standard package, therefore set it up with
- sudo apt-get install siege
Siege has two modes of procedure: internet and standard. Online mode simulates site visitors searching the goal internet site, while benchmark mode makes demands since quickly due to the fact internet host are designed for. We shall first run Siege in internet mode.
Internet mode is wonderful for gradually accumulating the strain regarding the host by increasing how many simultaneous site visitors as time passes. This mode also can produce a load that is sustained a long duration, which can be of use if you want to uncover what occurs to your site's performance during operations like producing backups.
Change to your residence directory and commence Siege in internet mode. If you'd like to try against HTTP-only details, replace
urls.txt. In the event that you accompanied action 5 and wish to test against HTTPS details, replace
- cd ~
- siege --internet --concurrent=5 --time=30S --log="siege-internet.log" --file="urls_file"
--internetsets Siege to mode that is internet
--concurrentmay be the amount of people to simulate. Inside instance,
we told Siege to simulate 5 users that are concurrent generate some traffic without overwhelming the server. You can increase this number as needed.( as you get more familiar with your server's capabilities,*****************)
--timeis just how long Siege will run for. This value could be set with
Mfor moments, and
Hfor hours. Inside instance, we told Siege to perform for 30 moments, once again, to build some traffic without overwhelming the host. As time goes on, you are able to test out various lengths of the time to observe your host reacts to a load that is sustained of.
--logmay be the way to the positioning you would like Siege to create its test outcomes to. Automatically, this location is
/var/log/siege.logand needs privileges that are sudo
--filemay be the way to the file containing the URLs that Siege use the test.
when you initially begin Siege, it states the variation quantity you're utilizing plus the amount of concurrent users its simulating. Then, you are told by it your test has started.
Siege production at begin of Run** SIEGE 3.0.8 ** planning 5 users that are concurrent battle. The host is currently under siege...
Once Siege has finished its run or perhaps is ended with
CTRL+C, it will likewise show the outcomes regarding the test combined with the precise location of the outcomes log file.
Siege production at End of Run... Raising the host siege... done. Deals: 157 hits Accessibility: 100.00 per cent Elapsed time: 29.72 secs Information transferred: 0.15 MB Reaction time: 0.49 secs Deal price: 5.28 trans/sec Throughput: 0.01 MB/sec Concurrency: 2.59 Effective deals: 161 Failed deals: 0 Longest deal: 0.74 Shortest deal: 0.27 FILE: siege-internet.log You'll disable this message that is annoying modifying the .siegerc file at home directory; modification the directive 'show-logfile' to false.
As the data within the production are complex, we are going to explore them in-depth in action 7.
Now, let us run Siege in benchmark mode to find the number that is maximum of requests the site is capable of serving at a time. This is information that is useful wanting to determine which extra technologies may enhance your web site's performance. In addition, benchmark mode can emphasize resource bottlenecks, we examine this mode more closely in Step 8.( as you will see when*****)
Start Siege once again, this time around in benchmark mode, simply by using
--benchmark in the place of
- siege --benchmark --time=30S --log="siege-benchmark.log" --file="urls_file"
The production follows the format that is same prior to, except that time the outcomes are very different as the mode ended up being various.
Siege Output** SIEGE 3.0.8 ** planning 5 users that are concurrent battle. The host is currently under siege... Raising the host siege... done. Deals: 444 hits Accessibility: 100.00 per cent Elapsed time: 29.72 secs Information transferred: 18.16 MB Reaction time: 0.49 secs Deal price: 105.28 trans/sec Throughput: 4.41 MB/sec Concurrency: 14.14 Effective deals: 421 Failed deals: 0 Longest deal: 0.74 Shortest deal: 0.27 FILE: siege-benchmark.log You'll disable this message that is annoying modifying the .siegerc file at home directory; modification the directive 'show-logfile' to false.
As with all the data from internet mode, the data from benchmark mode are complex. We shall explore them in-depth in procedures 7 and 8.
Now we can explore the output in greater detail and make practical use of the statistics.( that we have tested and benchmarked your site with Siege,*****)
Step 7 — Understanding Siege's Outcomes
about understanding your internet site's performance, determining bottlenecks, and determining where you can concentrate your upgrade efforts, Siege could be a asset that is powerful. The statistics it provides cover a range of metrics that can give you insights that are deep your internet site's health.
As we saw in action 6, Siege's production generally speaking appears like:
Siege production at End of Run... Deals: 904 hits Accessibility: 97.41 per cent Elapsed time: 4.59 secs Information transferred: 4.37 MB Reaction time: 0.07 secs Deal price: 196.95 trans/sec Throughput: 0.95 MB/sec Concurrency: 12.86 Effective deals: 904 Failed deals: 24 Longest deal: 1.95 Shortest deal: 0.00 ...
Specifically, these metrics suggest:
Transactionsmay be the number that is total of that Siege made.
Availabilitymay be the per cent regarding the demands your internet host taken care of immediately, including 4xx and 5xx-level error that is HTTP.
Elapsed timeis just how long the test went.
Data transmittedmay be the amount that is total of Siege utilized testing your website.
Response timemay be the amount that is average of the internet host took to answer a demand.
Transaction ratemay be the number that is average of per second your internet host served.
Throughputmay be the quantity of information per second your internet host served.
Concurrencymay be the number that is average of simultaneous connections.
Successful dealsmay be the final number of deals which were taken care of immediately with an status that is HTTP of not as much as 400.
Failed dealsmay be the number that is total of that had been taken care of immediately with HTTP status codes higher than 400.
Longest dealmay be the time your longest demand took to accomplish.
Shortest dealmay be the time your shortest demand took to accomplish.
Transaction rate plus the
Failed deals give you the fastest litmus test of the internet host's health.
Transaction rate represents the rate of the internet site, since it may be the amount of pages per second that your particular internet host can provide. The larger this true number is, the more visitors your website can handle and the faster the visitors will receive each page. That you want to increase.( if you are using Siege to improve your website's general responsiveness, this is the number*****)
Failed deals value describes any reaction on the internet host which has one rule, such as for instance
503 provider Unavailable. These mistakes frequently indicate issues like a database which not able to manage the true number of requests it is receiving or a web server that ran out of RAM. If this true quantity is such a thing besides zero, you should think of your online host's log files to see precisely which mistakes have actually happened also to get way on how to resolve the difficulties.
As you make modifications to improve your
Transaction rate and minimize your
Failed deals as time passes, keep in mind to consult the log file you create with every run of Siege, you see in your terminal as well as the date and time of the test as it includes all of the same statistics. This will help you track the trajectory that is overall of efforts.
Now we've analyzed Siege's production to ascertain your online host's rate and robustness, it is time to observe we could utilize this information that is same recognize and eliminate performance bottlenecks.
Step 8 — Distinguishing Efficiency Bottlenecks
In benchmark mode, Siege makes as numerous demands per 2nd due to the fact internet host is effective at serving. As soon as the host strikes the utmost amount of pages it may provide, this has reached a resource restriction.
The four many resources that are likely be impacted are:
- Network bandwidth
To get the maximum benefit from benchmark mode, you will need to run several extra tools within time that is same Siege, to be able to be wary of what occurs across the body as Siege increases its test load.
You can monitor 1st three resources — RAM, Central Processing Unit, and disk use — with top, something that delivers a powerful, real-time view of system resources.
Ubuntu includes top automagically, so that you don't have to set it up. Just run the demand,
The information shown in top is divided into two parts.
Sample top Outputtop - 21:02:32 up 50 min, 1 individual, load average: 0.07, 0.02, 0.00 Tasks: 102 total, 1 running, 101 resting, 0 stopped, 0 zombie %Cpu(s): 37.3 united states, 7.3 sy, 0.0 ni, 99.3 id, 8.3 wa, 0.0 hi, 0.0 si, 0.0 st KiB Mem : 1015200 total, 63536 free, 431456 utilized, 520208 buff/cache KiB Swap: 0 total, 0 free, 0 utilized. 512308 avail Mem PID CONSUMER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3249 www-data 20 0 469592 92276 33488 D 24.6 9.1 0:05.01 apache2 3239 www-data 20 0 442836 75080 41896 S 5.6 7.4 1:31.97 apache2 3572 www-data 20 0 424372 35272 21164 S 4.0 3.5 0:02.69 apache2
The top part, consists of 1st five lines of production, shows a listing of the present system use.
The reduced part shows a listing of the server that is individual presently operating on the machine along side each procedure' recognition quantity, owner, concern, good value, digital memory usage, real memory usage, shared memory usage, status, per cent of Central Processing Unit usage, per cent of memory usage, total time of task, and title.
While top is a tool that is useful handling procedures and monitoring CPU usage, in cases like this, we should see just what it may inform us about our bodies beneath the duress of a Siege standard test.
The Central Processing Unit use checks out,
%Cpu(s): 37.3 united states, 7.3 sy,. These values inform us your individual procedures are eating 37.3per cent regarding the Central Processing Unit, plus the operational system processes are consuming 7.3%. You will get the total CPU usage.( if you add these two values together,*****)
If your host is operating at or near 100per cent Central Processing Unit use, check out the entries that are top the list of processes to see if one or more are consuming unusually high amounts of CPU. If so, consider fine-tuning or reconfiguring the procedures to utilize less Central Processing Unit. If that is extremely hard, you might must update the CPU in your host.
Now, let us examine memory use.
Sample top Outputtop - 21:02:32 up 51 min, 1 individual, load average: 0.21, 0.47, 0.80 Tasks: 102 total, 1 running, 101 resting, 0 stopped, 0 zombie %Cpu(s): 17.4 united states, 3.4 sy, 0.0 ni, 79.2 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st MiB Mem : 991.406 total, 223.914 free, 395.621 utilized, 371.871 buff/cache MiB Swap: 0.000 total, 0.000 free, 0.000 utilized. 526.156 avail Mem PID CONSUMER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3249 www-data 20 0 469592 92276 33488 D 24.6 9.1 0:05.01 apache2 3239 www-data 20 0 442836 75080 41896 S 5.6 7.4 1:31.97 apache2 3572 www-data 20 0 424372 35272 21164 S 4.0 3.5 0:02.69 apache2
By standard, RAM use is shown in kilobytes regarding the line that is fourth. In the example that is preceding, we now have currently pushed
SHIFT+E when, transforming the worth to megabytes to really make the figures more straightforward to make use of. Press
SHIFT+E a time that is second transform the worth to gigabytes, and continue pushing
SHIFT+E to cycle back once again to the standard kilobytes display.
total value may be the amount that is total of available on the server. Keep in mind that the kernel reserves some memory on boot, so a 1024 MB machine shall show 991 MB of memory right here.
avail Mem shows the total amount of staying memory regarding the system. This quantity can get smaller as more RAM is employed and can sooner or later strike zero if you have no memory that is remaining regarding the host.
As with Central Processing Unit use, if
avail Mem is operating at or near zero, examine the record of procedures for entries that eat unusually high quantities of memory. If at all possible, reconfigure or fine-tune those procedures to utilize less memory or update the total amount of RAM in your host.
Finally, let us check disk use.
Sample top Outputtop - 21:02:32 up 52 min, 1 individual, load average: 0.21, 0.47, 0.80 Tasks: 102 total, 1 running, 101 resting, 0 stopped, 0 zombie %Cpu(s): 17.4 united states, 3.4 sy, 0.0 ni, 79.2 id, 31.6 wa, 0.0 hi, 0.0 si, 0.0 st KiB Mem : 1015200 total, 63536 free, 431456 utilized, 520208 buff/cache KiB Swap: 0 total, 0 free, 0 utilized. 512308 avail Mem PID CONSUMER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3249 www-data 20 0 469592 92276 33488 D 24.6 9.1 0:05.01 apache2 3239 www-data 20 0 442836 75080 41896 S 5.6 7.4 1:31.97 apache2 3572 www-data 20 0 424372 35272 21164 S 4.0 3.5 0:02.69 apache2
The disk use we have an interest in, I/O delay, just isn't just how much disk area can be acquired but just how much disk access is slowing the host. Disk access, particularly on a host that utilizes platter that is spinning disks, is extremely sluggish, and whenever the host accesses the disks, the Central Processing Unit must wait for information become retrieved.
Top reports these details due to the fact
wa value. The percent is indicated by it of time that the CPU(s) are sitting idle waiting for data from the disk. This number should close be as 0.0 possible.
In the preceding instance, the
wa value is
31.6. Which means the Central Processing Unit is investing a third of its time looking forward to information from disk. This is certainly a great deal of time, and it'll seriously influence performance that is website
I/O delay is generally the consequence of accessing the disk for files or making duplicated phone calls to databases that are local. If
wa is much over 0.0, consider moving static resources to a location that is remote like a content distribution community (CDN), or investigate approaches to lessen the amount of trips your applications make with their relevant neighborhood databases.
Q to leave top.
The last resource we will appear at is community use. Observe this, we shall make use of the Bandwidth track brand new Generation device.
Install this device with
apt-get run it with then the demand,

In this guide, we utilized the Siege benchmarking device plus the proxy that is sproxy to generate a configurable load on a web server and push it to its maximum throughput. These tools are extremely useful for any website deployment, as they help to pinpoint performance issues and plan upgrades that are well-informed
For another solution to reduce disk I/O and memory bottlenecks, take a good look at Varnish HTTP Cache. Varnish is an reverse that is easy-to-use that shops fixed internet site assets, reducing both RAM use and disk I/O.
If your internet site utilizes PHP, start thinking about setting up PHP-FPM instead of the PHP that is standard implementation. PHP-FPM reduces the CPU requirements for serving web that is PHP-based, thus quickening your whole internet site.
