CloudLinux - OptimumCache Feature

A super-performing density enhancer that optimizes servers with WordPress, Joomla, and others



OptimumCache (discontinued)

Our mission at CloudLinux is to deliver the most stable and profitable servers. With OptimumCache, you can expect increased server performance, increased density, and reduced server load by 20-30%!

Today, a typical shared hosting server encompasses multiple Web sites that are using WordPress, Joomla, Magento, and other popular software. This software is composed of exactly the same files, yet the files have to be separately loaded for each website, wasting both server IO and memory. OptimumCache solves these problems by creating a cache of duplicate files on the disk. All duplicates get loaded from a singular copy of the file, creating only one instance in the memory cache. The system bypasses disk IO for duplicates, thus significantly improving the speed of reading duplicate files, decreasing memory footprint, and increasing cache usage, all while lowering the load on the hard disk.



What can OptimumCache deliver? 

With OptimumCache, you can expect increased server performance, increased density, and reduced server load by 20-30%. The best results are shown for hosting servers running a large number of similar web applications, like WordPress, Joomla, Magento, etc.


Improved Server Performance   Improve Server Density by additional 30%
If you have significant IO wait times, you can see major performance improvements with OptimumCache. We have seen page speed improvements of up to 20% after OptimumCache was deployed. Here is what our customers have found:
  • Average system CPU usage decreased by 30%
  • Average IO wait time decreased by 52%
  • Average total CPU usage decreased by 25%
  • Average disk utilization decreased by 50%
  • Latency for popular URLs improved up to 20%
  In shared hosting, the disk subsystem is one of the common bottlenecks on the server. OptimumCache is able to significantly decrease the load on the disks, removing the bottleneck and providing you with the ability to host more customers on the same hardware.
