What is OptimumCache

DEPRECATED. Please read https://www.cloudlinux.com/cloudlinux-os-blog/entry/optimumcache-a-feature-of-cloudlinux-os-has-been-discontinued

Typical shared hosting server runs a number of sites with WordPress, Joomla as well as other popular software. This usually represents as hundreds of duplicate files that are constantly being read into file cache – both wasting precious disk IO operations as well as memory. OptimumCache creates a cache of such duplicate files.

With OptimumCache, if a duplicate of an already loaded file is requested, the file gets loaded from filesystem cache. By doing that, system bypasses disk IO, significantly improving the speed of reading that file, while lowering load on the hard disk. As the file had been read from disk just once, it is cached by filesystem cache just once, minimizing amount of duplicates in filesystem cache, and improving overall cache efficiency. This in turn reduces memory usage, decreases the number of disk operations – all while improving the websites response time.

OptimumCache comes free with CloudLinux. It requires 64 bit version of CloudLinux 6.x, as well as ext4 file system to work.
