Compare WordPress Performance on LiteSpeed, Apache, Nginx, and Cache Plugins 2021-01-19 17:50:39 Compare WordPress performance on LiteSpeed Web Server Vs. Apache and Nginx using LSCache, WPRocket, W3TC, and FCGI cache solutions.

LiteSpeed WordPress is up to 12X Faster!

For WordPress, LiteSpeed delivers the goods faster than any other HTTP/2 server.

Up to 12 times faster than nginx!

  • Benchmark Overview

    We tested HTTP/2 implementations from LiteSpeed Web Server, nginx, and Apache, to see how they would compare when loading WordPress. LiteSpeed beat nginx by up to 12X, and blew Apache out of the water by a whopping 84X! The best available WordPress cache plugins were used for each server: LSCache for LiteSpeed, FastCGI Cache for nginx, and W3 Total Cache for Apache.

    We followed the methodology laid out on, which means our results are verifiable and repeatable.


    HTTP/2 Test Results

    h2load -n 100000 -c 100 -t 1 -T 5 -m 10 -H 'Accept-Encoding: gzip,deflate'

    Nginx 6025.3 24.5 0 26.54%
    Apache 826.5 3.08 0 88.9%

    LiteSpeed Web Server performs 12X faster than Nginx and 84X faster than Apache when loading WordPress.

    litespeed cache for wordpress vs. other cache Plugins

    Test Results

    We compared the speed at which different web servers and caching platforms respond to requests for WordPress pages on a cPanel setup, using both non-keep-alive and keep-alive connections.

    Our test platforms included:

    • LiteSpeed Enterprise (LSWS) using the popular W3 Total Cache and WPRocket WordPress cache plugins, as well as with our LiteSpeed Cache Plugin for WordPress.
    • Apache using the W3 Total Cache and WPRocket WordPress cache plugins.

    Our results showed Apache (with keep-alive enabled) peaking around 1,300 and 700 requests per second with W3TC and WPRocket, respectively.

    With the exact same setup, LSWS with W3TC and WPRocket delivered around 4,800 requests per second, an improvement factor of over 2.6x or 6x respectively.

    Using the LiteSpeed Cache Plugin for WordPress with LSWS easily handled close to 5,200 requests per second.


    LSWS with LSCache Performance Gain

    Concurrent Users Keep-Alive Apache / WPRocket Apache / W3TC Nginx / FCGI LSWS / W3TC LSWS / WPRocket
    10 No 5.6x 3.2x 4.9x 1.2x 1.2x
    Yes 7.4x 4.0x 6.4x 1.1x 1.1x
    100 No 5.7x 3.2x 5.0x 1.2x 1.2x
    Yes 6.3x 3.5x 5.0x 1.1x 1.1x


    • Default configurations were used when possible.
    • Rewrite rule caching was used for W3TC and WPRocket to ensure maximum peformance.
    • The test was performed over a 10GBps network connection to make sure network bandwidth did not become a bottleneck.
    • The benchmark simulated serving 10,000 requests to 10 and 100 users.

GDPR Statement

LiteSpeed Technologies values your users’ privacy. Although our software does not directly collect any personally identifiable information from visitors to your site, LiteSpeed may still be considered a data processor, as user information may be temporarily cached and/or logged, as outlined in this document.


LiteSpeed Web Server, OpenLiteSpeed, LiteSpeed Web ADC, and related software may record IP addresses as a part of normal logging. An access log and an error log may record visitor IP addresses and URL visited. The logs are stored locally on the system where LiteSpeed server software is installed and are not transferred to or accessed by LiteSpeed employees in any way, except as necessary in providing routine technical support if you request it. This logging may be turned off through configuration. It is up to individual server administrators to come up with their own schedule for removing such logs from the file system.

Cache Solutions

Our cache plugins potentially store a duplicate copy of every web page on display on your site. The pages are stored locally on the system where LiteSpeed server software is installed and are not transferred to or accessed by LiteSpeed employees in any way, except as necessary in providing routine technical support if you request it. All cache files are temporary, and may easily be purged before their natural expiration, if necessary, via a Purge All command. It is up to individual site administrators to come up with their own cache expiration rules.

LSCache for WordPress

In addition to caching, our WordPress plugin has an Image Optimization feature. When optimization is requested, images are transmitted to a remote LiteSpeed server, processed, and then transmitted back for use on your site. LiteSpeed keeps copies of optimized images for 7 days (in case of network stability issues) and then permanently deletes them.

Similarly, the WordPress plugin has a Reporting feature whereby a site owner can transmit an environment report to our server so that we may better provide technical support.

Neither of these features collects any visitor data. Only server and site data is involved.

Support Services

Sometimes, when you request technical support, LiteSpeed may ask for login credentials to various areas of your site. You may refuse to share such credentials, however refusal may impact LiteSpeed’s ability to provide the requested support services.

Upon completion of a support ticket, LiteSpeed immediately deletes all login credentials you may have shared.

Any user data encountered by LiteSpeed is kept strictly confidential. We never provide your support ticket information to any third party without your explicit consent.
