Help:Caching

Cache (or caching) is specified as an storage mechanism were earlier computed values are stored separately from the original request and hereby enable future requests to be served faster using the already computed results.

The general suggestions (where feasible) is to use CiteRef::infoworld.com:3063161CiteRef::redis.io:benchmarksCiteRef::antirez.com:94CiteRef::doc.owncloud.org:redis:apcu as cache backend to ensure that large blob objects can be stored and retrieved without impacting the general performance.

Technical aspects

 * 1) HtmlCache
 * 2) WebCache (eg. Squid)
 * 3) ParserCache
 * 4) QueryCache

Configuration settings
Caching (either temporary or persistent) is an important part of MediaWiki's storage strategy and also became an infrastructural component in recent Semantic MediaWiki releases to ensure that editing and viewing experience is improved. It further helps to reduce the amount of computational tasks performed required by Semantic MediaWiki.

An expensive (and memory intensive) task is MediaWiki's  with responsibility to turn wikitext into a HTML representation. It also includes processing (or signalling) extension to add or modify data before the output is produced.
