mod_fcgid with php opcode caching

I have been using apache web server with mpm-worker and mod_fcgid.

I have read about mod_fcgid that it can not make use of opcode caching.

apc cache module seems to be enabled in my php configuration.

I am not sure if my spawned php codes are never shared.

Should I remove APC? Does it have any overhead?

    As for the overhead, if you have n processes, then you'll have n caches. It's not space efficient but it might still help reducing CPU cycles tho.
