    Hello!

    How can I use Opcode Cache with APC instead of Zend? I did use APC for all cache options in the past but it’s no longer available for the Opcode Cache and I get sudden server load spikes up to 50 even without any huge traffic. The only way to calm it down so far was a switch to “Disc: Enhanced” caching for the Page Cache.

    Hello @wpdoode

    Thank you for reaching out and I am happy to help!

    APC is good, it lacks some features found in Zend’s offering and additionally lacks maintainers to bring it up to speed for the latest PHP versions.

    If you experience dproblem with the APC for Page Cache, what is the specific reason to switch from Zend?

    Thanks!

    My webhoster must have changed something. The APC option suddenly dissapeared.

    However the “Disc: Enhanced”?page cache option appears to be more effective than APC caching because cached pages are usually served like static html files with almost no php interaction and the cache even works when I put WordPress into maintenance mode. The short server load spikes are still there but only affect work in the WP-Admin area.

    These are my current settings:

    Page Cache: Disc: Enhanced
    Opcode Cache: Zend Opcache
    Database Cache: No in use
    Object Cache: APC
