WP Super Cache

WP Super Cache
WP Super Cache

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

The static html files will be served to the vast majority of your users:

  • Users who are not logged in.
  • Users who have not left a comment on your blog.
  • Or users who have not viewed a password protected post.

99% of your visitors will be served static html files. One cached file can be served thousands of times. Other visitors will be served custom cached files tailored to their visit. If they are logged in, or have left comments those details will be displayed and cached for them.

The plugin serves cached files in 3 ways (ranked by speed):

  1. Expert. The fastest method is by using Apache mod_rewrite (or whatever similar module your web server supports) to serve “supercached” static html files. This completely bypasses PHP and is extremely quick. If your server is hit by a deluge of traffic it is more likely to cope as the requests are “lighter”. This does require the Apache mod_rewrite module (which is probably installed if you have custom permalinks) and a modification of your .htaccess file which is risky and may take down your site if modified incorrectly.
  2. Simple. Supercached static files can be served by PHP and this is the recommended way of using the plugin. The plugin will serve a “supercached” file if it exists and it’s almost as fast as the mod_rewrite method. It’s easier to configure as the .htaccess file doesn’t need to be changed. You still need a custom permalink. You can keep portions of your page dynamic in this caching mode.
  3. WP-Cache caching. This is mainly used to cache pages for known users, URLs with parameters and feeds. Known users are logged in users, visitors who leave comments or those who should be shown custom per-user data. It’s the most flexible caching method and slightly slower. WP-Cache caching will also cache visits by unknown users if supercaching is disabled. You can have dynamic parts to your page in this mode too. This mode is always enabled but you can disable caching for known users, URLs with parameters, or feeds separately. Set the constant “DISABLE_SUPERCACHE” to 1 in your wp-config.php if you want to only use WP-Cache caching.

Light Speed Cache

Light Speed Cache

LS Cache is a server-side page cache. Page caches save time and resources, and they do so by storing the full content of dynamically-generated pages so that static copies may be served to the user.

LSCache, in particular, because of its close relationship with the server, can remember things about the cache entries that other plugins cannot, and it can analyze dependencies. It can utilize tags to manage the smart purging of the cache, and it can use vary cookies to serve multiple versions of cached content based on things like mobile vs. desktop, geographic location, and currencies.

Comet Cache

Comet Cache
Comet Cache

If you care about the speed of your site, Comet Cache is one of those plugins that you absolutely MUST have installed 🙂 Comet Cache takes a real-time snapshot (building a cache) of every Page, Post, Category, Link, etc. These snapshots are then stored (cached) intuitively, so they can be referenced later, in order to save all of that processing time that has been dragging your site down and costing you money.

The Comet Cache plugin uses configuration options that you select from the options panel. See: Comet Cache -› Options in your Dashboard. Once a file has been cached, Comet Cache uses advanced techniques that allow it to recognize when it should and should not serve a cached version of the file. By default, Comet Cache does not serve cached pages to users who are logged in, or to users who have left comments recently. Comet Cache also excludes administrative pages, login pages, POST/PUT/DELETE/GET(w/ query string) requests and/or CLI processes.
