..44% tart regression on windows xp after the central -> aurora merge
tart regressed on windows xp when we merged central to aurora 2 weeks ago: http://graphs.mozilla.org/graph.html#tests=[[293,52,37],[293,1,37],[293,132,37]]&sel=1393701595288,1396293595288&displayrange=30&datatype=running it is hard to determine what really happened, but it looks like this merge from b2g-inbound might be the root cause: http://hg.mozilla.org/mozilla-central/pushloghtml?changeset=d2dac18d0562 of course I don't see a bug from early march to call this out. I know there were 2 weeks where I wasn't watching the tree as much and that would be right in the middle of that. I wanted to get this on the books. avi, did we rewrite tart and expect a regression?
(In reply to Joel Maher (:jmaher) from comment #0) > I wanted to get this on the books. avi, did we rewrite tart and expect a > regression? No and no.
did some retriggers, we don't run these tests on b2g-inbound, so I need to work of m-c for now: https://tbpl.mozilla.org/?fromchange=32a41942974c&tochange=ff96e428da76&jobname=Windows%20XP%2032-bit%20mozilla-central%20talos%20svgr
ok, down to this change from inbound: https://hg.mozilla.org/mozilla-central/pushloghtml?startID=26364&endID=26365
this is the offending changeset: https://hg.mozilla.org/integration/mozilla-inbound/rev/45ac7b7d7466 you can see the jump from ~5.33 to ~5.45 https://tbpl.mozilla.org/?tree=Mozilla-Inbound&jobname=Windows%20XP%2032-bit%20mozilla-inbound%20talos%20svgr&fromchange=45363136618e&tochange=af1a435e117a and more love from graphs: http://graphs.mozilla.org/graph.html#tests=[[293,1,37],[293,52,37],[293,132,37],[293,94,37],[293,131,37]]&sel=1393972489994.252,1394480606680.3665&displayrange=30&datatype=running

bbouvier, this hasn't been getting much attention, Aurora will be going to beta in the near future. Can you take a look at this?
I mixed up my need info, actually jdemooij, can you comment on this bug?

30 is our Beta now, if this is an unexpected performance change then please report in the bug about the options available for addressing it: backout offending patch, forward/speculative fix (would have to be ready to uplift in the next 2 weeks), or if there's nothing that can be done.
Sorry for the delay. This is basically the same as bug 987900 comment 8; hard to fix without adding more complexity or regressing perf elsewhere. Joel, is this WinXP only?

Sounds to me like a great candidate for wontfix.
as far as I can tell this is winxp only. Looking on datazilla: https://datazilla.mozilla.org/?start=1397730697&stop=1399816204&product=Firefox&repository=Mozilla-Beta&os=win&os_version=5.1.2600&test=tart&graph_search=c95ac01e332e&tr_id=5303331&graph=icon-close-DPI1.error.TART&x86_64=false&project=talos we have these subtests regressing: icon-close-DPI1.error.TART icon-close-DPI2.error.TART simple-close-DPI1.error.TART Looking at the overall picture (not worrying about a this specific issue), the uplift to beta didn't show any regressions, only what could appear to be slight improvements.
