AIUI many of our machines have very slow hard drives, but releng is in the process of fixing this. The slow drives may be to blame for the statistic I keep hearing, that pymake (plus -j4) isn't a win on Windows. If we can prove that pymake is a substantial win, I bet bug 593585 would gain some momentum.

just did a quick run on w32-ix-slave34. Using http://hg.mozilla.org/mozilla-central/rev/d963476cbf67, our debug mozconfig with mk_add_options MOZ_MAKE_FLAGS=-j4, and time python -OO build/pymake/make.py client.mk build took 26:13. A noop build right after that took 6:52. Since august 8th our build machines have range from 10:21 to 2:15:00 with an average of 50:06. So this looks like a big win to me!
