PHP extension Zend Opcache - should we use it or not?
We have some code in CMSB already to work with/around opcache. But it is a fairly common extension, so if you want to try it out and you run into any problems we can help you debug/resolve it as part of free support. We want to make sure CMSB is fully compatible with these features.
In the worst case, if it had a problem you could just have the tech turn it off again.
