That raised a second question: do you collect branch / hotness info during lower tier jitted code run, so as to improve performance of higher tiers ? > Separately, we often use non-pgo builds for quick checks, so we also have > the system I described that makes our non-pgo build more reliable by using > the function ordering from the pgo build. ok. Are you just « putting hot stuff in the hot section » or did you try to specify an ordering to further improve locality? (I don't know if it's possible, it's mentionned in one of the paper) Thanks, Serge _______________________________________________ Speed mailing list Speed@python.org https://mail.python.org/mailman/listinfo/speed
