One of the most crucial WordPress plugins we recommend having installed is a caching plugin. There are several reasons for utilizing a cache plugin, the primary reason being pageload speed improvements.
Our favorite of the bunch, the only issue we’ve ran into is that it requires your server be running PHP version 5.3, which might not always be the case.
If you care about the speed of your site, Quick Cache is one of those plugins that you absolutely MUST have installed. Quick 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.
This seems to be the crowd favorite WordPress cache plugin, though we find it to be unnecessarily complicated. Perhaps we’ve just been spoiled by the ease of use offered by QuickCache. That said, its many options likely provide some added oomph to its performance that we non-technical types only wish we understood.
The only WordPress Performance Optimization (WPO) framework; designed to improve user experience and page speed. W3 Total Cache improves the user experience of your site by increasing server performance, reducing the download times and providing transparent content delivery network (CDN) integration.
An oldie but a goody, WP Super Cache is solid enough to warrant being pre-installed by HostGator should you utilize their one-click WordPress install app. It’s plenty good enough to get the job done, but the above are more polished.
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.
