Depends on what you're using in your APC configuration, but generaly
eAccelerator seems to perform a bit better than APC currently. In our
experience APC has never crashed though ( php 5.1.6 FC6 ), and there
are a number of things we can do to optimize it still, for example
changing the locking strategy from file locks to spin locks like
FaceBook does.
