W3-Total Cache – mysql query cache

  • I have W3TC and I just switched my hosting to VPS and then immediately added PHP APC so I could save to that instead of to a disk for my caching method…what is mysql query cache? Do I need it with W3TC if I have PHP APC and is mysql query cache recommended to make my site perform better? If you would recommend mysql query cache, where can I find it?

    Disk enhanced is fastest.

    what is mysql query cache?

    This is a MySQL server cache setting which reduces the response time for common queries quite a bit. So it has nothing to do with W3TC, instead it’s part of MySQL’s own caching. You should make sure it’s running and tuned. Normally my.cnf is the file to look for to edit MySQL settings.
