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.

opcache is server configuration. It pertains to how you install the server, not WHMCS.
I actually asked the support department and this is the replay I got:

Hi Ram,

Thank you for contacting WHMCS!

We have a guide on this here:

WHMCS does not support opcache caching. The presence of this extension has been known to cause unexpected behavior with the WHMCS Software, and therefore we recommend disabling it on systems running WHMCS.

Feel free to contact us if you have any questions or concerns.
