Today ROVworld.com implemented a new caching system on their website. 

The page load times had been slowing down due to the large amount of information stored in the database and increased connections to the database.

As a result of the upgrade page loading speed has now improved dramatically and, as a result, members can now experience quicker access to various areas in the site.
