How well does APC (latest version 3.1.5) work with PHP FastCGI (especially PHP-FPM)?
There are a lot of articles stating that they don't work together pretty well but these references are also very old (like 2009).
Also, can the opcode cache be configured separately between PHP-FPM pools?
And finally what's the best configuration for sharing the opcode cache between FastCGI processes (mmap'ed /tmp/apc.XXXXXX
, shm mmap'ed /tmp/apc.shm.XXXXXX
or anonymous mmap'ed /dev/zero
)?
