Hey everyone,
A performance regression has appeared on the XP Perf bot in the morejs page

Probably caused by jemalloc. Jim was experimenting with the idea of getting
some dev-channel data from using jemalloc as opposed to tcmalloc. I'm not
surprised there was a perf delta, but I am surprised by how much. The DOM

I'm quite sure it is jemalloc. I failed miserably by not over-communicating
this checkin. My apologies to all that I have inconvenience.
We have just this week identified a number of misteps in our use of
TCMalloc. I think that we can eventually reach an excellent result with
TCMalloc... and we
I think we should be willing to take a temporary performance hit on the dev
channel in the interests of generating data which will eventually improve
stability.
Could we set jemalloc on selected renderer processes? I realize that
wouldn't necessarily only impact the target domains, but it might

Thanks Darin, Mike, and Jim for the quick response. Sounds like we'll have
this in the trunk for a couple days at least if not longer, so I updated the
XP perf expectation. The builder should stay green for now.
