WordPress is among the most popular open source publishing platforms on the planet. Out-of-the-box it performs in any hosting environment, but with W3 Total Cache, site performance is maximized leveraging the suite of tools it provides. User experience is one of the most important factors in site success and to improve it, reducing response times of your site is vital. Studies show that the faster your site loads, the longer visitors will stay, the more pages they will visit, the lower any learning curves become and the more favorably Google will rank your site. There are lots of optimizations W3 Total Cache does unobtrusively, without modifying plugins, theme, database etc.
Let’s take a look at some settings to get you started:
Reduce load by caching pages and feeds after the first request (or even prime the cache if you prefer) and returning the saved file from either disk or memory.
Recommended Setting: Disk (enhanced)
Recommended Setting: Disk
Reduce read operations on the database by caching responses for a short time. Consequently, the time required to generate new pages is also reduced. The result is that the response time after users post new comments, perform searches or request a page that has not been cached is a low as possible.
Recommended Setting: Off, but varies by site, try disk and verify if performance increases.
A “higher level” cache than the database cache, the object cache is a “runtime” cache containing the various pieces of data needed
Recommended Setting: Off, but varies by site, try disk and verify if response times decrease.
Content Delivery Network:
Latency is among the easiest ways to improve the user experience (reduce load time) of a site. Rackspace Cloud Files can easily be enabled using W3 Total Cache on your site to allow WordPress core files, theme files and even the media library to be hosted on the Cloud Files Content Delivery Network by Limelight Networks. Site visitors will then have a highly responsive experience when browsing. Once Cloud Files account settings have been populated and desired files exported (uploaded), everything then works transparently; when new attachments are added to the media library they are automatically hosted with Cloud Files.
Recommended Setting: Rackspace Cloud Files
Recommended Setting: Defaults are a good start, experiment with settings to achieve desired policies.
User Agent Groups:
If your site has mobile users or if it uses various themes for respective groups of users. The User Agent Groups tab of the plugin allows you to assign groups of browsers or devices to use a specific theme or even redirect them to another web site. This feature also makes sure that specific browsers/devices have respective caches and therefore the lowest response times possible.
Recommended Setting: Defaults are a good start, settings may vary per site.
