And what happens when you go from A or B to C? Have you been running a top or systat -vmstat while this is happening? I'm thinking it might be a purely IO thing, on the proc box. I have seen similar slowness with the default FreeBSD install on single proc boxes, but a few sysctl's seem to do the trick.
