Is that really the usual case? For me it's about 90% PHP requests, and the
remaining CSS/JS/Image requests wont be sped up a bit by being served
through a smaller apache process, because they are already fast anyway.
Going FPM would thus mean about double the numberr of processes, and double
the number of context switches.
