Mike,
disabled eAccel in favor of memcached? Far as I know memcached is set to use
128MB of RAM at the moment. eAccelerator appears to be
set to use 32MB, if
that matters for answering the question.
eAccelerator caches bytecode, memcached does not.
Even then, if eAccelerator is used as bytecode cache, it is 10x faster than
memcached, because there's no more communication/serialization overhead.
