I'm currently running php5 with APC, the latter with default configuration. However after setting up munin to monitor APC, I'm surprised by the results:
- apc.shm_size: 30
- apc.gc_ttl: 3600
- apc.ttl: 0
- Used: 14MB
- Request rate: 100 requests/second
- Fragmentation: 0
- Hit ratio: 80% (dropping to 0 a few times per hour)
So the obvious question: how can I adapt the configuration to achieve a higher hitrate. I find it very strange that the available memory is not fully used which the hitratio is still below what I would expect.
Thank for any hints!
