Hello:
We have a very high-volume site that runs across a cluster of several
machines which needs to have access to our back end storage platform, which
needless to say is very busy. I have been given the task of reducing load to
the filer. Due to the fact that our application is rather large
I think the main hint you need is to never use require_once/include_once
with an opcode cache. Those are the only ones that will cause an open()
call. You should only be seeing a single stat() call per file under APC
(needed to get the inode+device hash key for the shared memory lookup).
Or simply use eAccelerator which does not cause those open
calls.
Rasmus, is that behaviour by design? I deinstalled APC
because of this 'characteristic' last week. It was killing a
high-traffic site.

Which is pretty fine for us PHP 4.4 users.
