Quite firefox, and do "./jprof firefox jprof.log >/tmp/profile.html". Let it sit for 5 minutes, then "kill -USR1 ". Then cd to objdir/dist/bin, start firefox (using a non-e10s profile) with env vars of JPROF_FLAGS="JP_DEFER JP_PERIOD=0.002". You could try building on either side of the regression (opt builds) with ac_add_options -enable-jprof in. Any details on the network setup, OS version, network config and HW would be hugely helpful.

My guess is it has to do either with networking differences between Ubuntu and Fedora, network driver differences (unlikely), or the network environment (in particular IPV6 addresses and LAN setup). My jprof runs aren't any use if I'm not seeing the effect. (Maybe it's 55-60% vs 57-63%, maybe - that's way less than anything reported, and in the noise floor). I don't see a CPU difference between 41 and 42, let alone on either side of the regression range. > The easiest way to reproduce the issue was disabling e10s (which makes CPU > I found the regression range using mozregression.
