LiteSpeed Web Server (LSWS) is proprietary web server software. It is the 4th most popular web server, estimated to be used by 10% of websites as of July 2021.[3] LSWS is developed by privately held LiteSpeed Technologies. The software uses the same configuration format as Apache HTTP Server and is compatible with most Apache features.[4][5] An open source variant[6] is also available.[7]
LSWS was released in 2003, and in August 2008 it became the 16th most popular web server.[8] In November 2016, LiteSpeed's market share grew from 0.39% to 3.29%, increasing its position from 10th to 4th most popular web server according to Netcraft.[9] In 2017, a team from Hong Kong Polytechnic University found it to be one of the six most popular web servers,[10] and it was estimated by a team at RWTH Aachen University to be running 9.2% of all HTTP/2-enabled websites.[11] As of April 2020, LSWS was used by 69.3% of websites using QUIC[12] and 47.6% of websites using HTTP/3.[13]
According to a Netcraft web server survey, LiteSpeed had not grown beyond 3% of global market share as of 2021.[14]
LiteSpeed Cache plugin, also known as LSCache, is a cache and performance management plugin for websites developed specifically for LiteSpeed Web Server. You can download this plugin from WordPress.
