Please add opcache caching to WHMCS
Please add support for opcache caching.
As far as I know it is the only solution officially supported by PHP developers. The benefits are increased performance and significantly lower memory usage.
However, opcode caching extensions (including OPcache, eAccelerator and APC) aren't compatible with servers configured to use some common types of high-security PHP handlers such as suPHP (the default on WHM / cPanel Linux servers) - I hope there is a way to overcome this problem add add opcache caching support to WHMCS.
