another thing to study is strace output... with timestamps and syscall
times.  "strace -r -tt -T -p child_pid" should do it.  you don't
necessarily need to trace all the children.  but you might as well trace a
few, you could add "-ff -o outputprefix" to get your output into useable

then look to see what your most expensive syscalls, and intra-syscall
times are.
