Disable APC Cache for cached files?

  • 772

I have a quite large website, in which there is a forum powered by phpBB. I have APC enabled with 1Gb of RAM. phpBB generates a lot of php files of cache (60 000-70 000 in my case), and they rapidly fill up APC memory. I was thinking to disable apc caching of such files through the apc.filter option. In your opinion, does it make sense?

  1. Playing with the filters option definitely makes sense. I would try that first.

    Otherwise, you can set apc.ttl to clean out the opcode cache entries after a set amount of time. It's set in seconds; try something like 3600 to start and adjust appropriately.

  2. It should be possible to turn off filesystem caching in phpBB. Your solution makes sense too.
