Best wordpress cache plugins to improve wordpress performance

Its necessary for your site to load faster even on any low bandwidth internet connection. For this purpose, there are lotz of cache plugins available under wordpress cache plugin directory. These cache plugins can be used to improve the load time of your site web pages and also the performance of your wordpress site. Here i’m going to list few popular plugins.

1. WP Super Cache – This plugin generates static html files from dynamic WordPress blog. After a html file is generated your webserver will serve that html file instead of processing the comparatively heavier and more expensive WordPress PHP scripts.

It serves static html files to the vast majority of users, like who are not logged in, who have not left a comment etc.

2. W3 Total Cache – This one is fastest and most complete WordPress performance optimization plugin. This plugin improves the user experience of your blog by improving server performance, caching every aspect of your site, reducing the download time of your theme and providing transparent content delivery network (CDN) integration.

This plugin is compatible with shared hosting, virtual private / dedicated servers and dedicated servers / clusters. You can store the cached files on memory or on disk or on CDN.

3. WP-Cache – This is an extremely efficient WordPress page caching system to make your site much faster and responsive. This plugin caches your blog pages and stores them in a static file for serving future requests directly from the static file rather than loading and compiling the whole PHP code and the building the page from the database.

This plugin allows you to enable or disable cache, define expiration time for static pages, define rules for rejecting and accepting which URLs and php files can be cached, and shows and delete pages in cache.

4. Hyper Cache – Hyper Cache is specifically written for people which have their blogs on low resources hosting provider. It works even with hosting based on Microsoft IIS. It has three invalidation methods: all the cache, single post based and nothing but with control on home and archive pages invalidation.

This plugin manages (both) plain and gzip compressed pages, uses compressed storage to reduce the disk space usage and autoclean system to reduce the disk usage.

These above listed plugins are html caching plugins, while there are some plugins which can be used to cache database queries.

DB Cache Reloaded – This plugin caches every database query for a given time of period. As this plugin caches database queries, it is much faster than other html caching plugins and also uses less disk space for caching.

This plugin works with wordpress 2.8 or later. For earlier versions of wordpress you can use DB Cache plugin.
