That's what I thought, but if I compare a checkout from earlier today (fbe7ac16d722f786e5f), I get: time make -j32 bootstrap real 2m21.046s user 16m34.325s sys 0m51.938s And with the current trunk it's: real 1m52.976s user 16m1.060s sys 0m52.892s *scratches head* That's a much bigger reduction -- 20% -- and it sounds just weird. Well, it's making all the loaddefs files now in under 2 seconds (it used to take 10 seconds for the main one and then the other ones fired off as separate compilation processes), but it still sounds oddly... too much. I'd take that with a grain of salt, but I can't explain it otherwise (unless there was something in particular wrong with fbe7ac16d722f786e5f -- perhaps I should try with a checkout from a couple days ago instead). -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
