have you tried any of the other op code caches? ones that might be less buggy
perhaps? ;-) eaccelerator, turckmmache etc.

would you delve into changing the code to speed things up or are you looking
for useful settings in configuration files?

is the directory where the session files are saved to in tmpfs? that should be
quicker than having too many writes to disk occur. (there's a use for the extra
ram you are getting!)

check which engines you are using with mysql - some are quicker than others.

if you aren't going to bother analysing the logs - turn it off [again less
resources used on non-essentials]

if you don't mind getting your hands dirty optimising the code there are quite
a few more options available.

also read http://phplens.com/phpeverywhere/tuning-apache-php - there are plenty
more gems of advice there.
