Compression/yo

This page is about data compression as it relates to MediaWiki.

Output

It is possible, with HTTP, to compress individual pages served. Both the browser and the server must support it, and it is normally negotiated, (with uncompressed version available). This is on by default if PHP has zlib support enabled (no Apache mods are required). The negligible CPU time spent compressing on the server is dwarfed by things like loading the PHP scripts, and the bandwidth savings are considerable.

See Manual:$wgUseGzip and Manual:$wgDisableOutputCompression for details.

Page histories

It is also possible to compress the history table in a way which exploits the similar data in the different versions, such as Reverse diff version control. See History compression for some actual numbers.
