Are LiteSpeed ​​servers really faster than Apache

Web server comparison: Apache vs Litespeed

This is really an update so people won't be misled when it comes to this question. was running on LiteSpeed. And was used to recommend LiteSpeed.

The reason was simply this:
Like most popular PHP applications, WordPress was written for Apache, which serves more than half of the web. However,'s sysadmins got fed up with Apache crashing under extremely heavy workloads and especially while deploying configuration changes. So you have chosen a super fast and super stable server (LiteSpeed) that is Apache compatible which is a drop-in replacement which means it just works with Apache settings including virtual hosts and .htaccess files.

The problem was that LiteSpeed ​​was commercial and WordPress had some pressure to live up to its open source ideals (LiteSpeed ​​was commercial ... a much more limited "standard" edition was available for free). . So switched to for nginx in 2008 and dropped its LiteSpeed ​​recommendation.

In mid-2013, OpenLiteSpeed ​​was published as an open source edition of the web server. Compared to LiteSpeed ​​Enterprise (the commercial edition), OpenLiteSpeed ​​does not have 100% Apache compatibility (e.g. .htaccess is not supported, Apache rewrite rules are supported, but must be included in the configuration file by .htaccess) cPanel, Plesk, VirtualMin etc for OpenLiteSpeed), Mod_security compatibility, and page cache (Enterprise Edition has page cache for static content, OpenLiteSpeed ​​doesn't ... although OpenLiteSpeed ​​can be used with Varnish so this isn't a huge hurdle represents).

With this in mind, the advantages of LiteSpeed ​​over Apache:

  • It is widely believed that most servers, including Apache, nginx, and LiteSpeed, are mostly comparable in terms of dynamic content performance.
  • With very high matches, LiteSpeed ​​is faster than nginx, which is faster than Apache.
  • LiteSpeed ​​and nginx are fantastic (and way ahead of Apache) when it comes to static content.
  • OpenLiteSpeed ​​is really doing some new, cool stuff like Google's SPDY protocol, while Apache is ditching the implementation.
  • LiteSpeed ​​is also likely using a fraction of the resources Apache is using for the same load ...
