Installing APC (Alternative PHP Cache) Can Enhance your WordPress W3 Total Cache Performance
This option really depends on the environment you’re hosted in and what kind of pages you’re serving. Typically, most websites are hosted in a virtual environment like our managed domains but may not have similar disk, CPU or memory resources that we deploy. If you have a good amount of CPU (1.5+ CPU cores) and 2 GB or more of RAM then I would recommend testing this method out.
Test out the APC Method to Determine if It Does Enhance W3 Total Cache Performance
We install APC (Alternative PHP Cache) on the cloud servers to allow the W3 Total Cache WordPress plugin better work its magic for high traffic WordPress blogs. The result is more pages, images and web components are cached in memory for quicker response times to the end user. When your WordPress website receives an influx of traffic, it’s much faster for the server to retrieve that data from memory than disk – this is typically the source of bottlenecks for the majority of WordPress Sites.
Configure WordPress Plugin – W3 Total Cache
At this point, you should configure your W3 Total Cache WordPress plugin to use Alternative PHP Cache for all components.
