Apc configuration values for a huge server

[ASTRAPI]

Hello

How do you recommend me to adjust the Apc settings on my server?

2x Intel Xeon Quad 5405
24gb ram ---> I have 8gb free)
4 x Sas disks 15k Raid 10


Now i use:

apc.enabled=1
apc.shm_segments=1
apc.shm_size=512M
apc.max_file_size=10M
apc.stat=0
apc.ttl=3600
apc.user_ttl=7200
apc.num_files_hint=10000
apc.user_entries_hint=10000
apc.enable_cli=1


Thank you

i switched from apc to xcache because of those nasty "potential cache slam" which made me mad!

What is "cache slam"?

[Luis Manson]

i think is when there is already something in a cache entry and for some reason something want to change its content
