According to our graph[1], between changesets 1cbed63f3eea and 401c71c3732d, we saw a marked drop in TART times for the UX branch, while the m-c branch seemed to stay the same.

We should find out why that happened.


Here are the changesets in that range:
Note that this improvement can be seen on the graph server graph happening in the points from May 2nd to May 3rd.
Avi and I suspect that either bug 850918 or bug 826689 caused this performance improvement.

I've pushed the May 3rd changeset to try, as well as a push with both of those bugs backed out, and a push with just bug 850918 backed out.

Back out both bug 850918 and bug 826689:
Back out bug 850918:

Hopefully that gives us some details on what happened here.
I pushed the May 2nd changeset to try as well, for a more complete picture:
We're not seeing a whole lot of improvement between our May 2nd and May 3rd try pushes... the backfilled data for those dates is a little suspect, so we're retriggering them to hopefully get a clearer sense of the picture.
Matt's awesome, came out of vacation, and helped clean up the data. Some data from some earlier runs were in there, and he's removed them.
