1099591 - 4% Linux32 Dromaeo DOM regression on inbound (v.36) Nov 13 from push 6cec52c43496

Status: RESOLVED WORKSFORME

(Testing :: Talos, defect)

Description

[Joel Maher ( :jmaher ) (UTC -8)]

Graph server outlines a regression (lower is worse):
https://tbpl.mozilla.org/?tree=Mozilla-Inbound&fromchange=0cf9d23846cd&tochange=d1962cb07ea5&jobname=Ubuntu%20HW%2012.04%20mozilla-inbound%20talos%20dromaeojs

I did some retriggers on tbpl:
https://tbpl.mozilla.org/?tree=Mozilla-Inbound&fromchange=0cf9d23846cd&tochange=d1962cb07ea5&jobname=Ubuntu%20HW%2012.04%20mozilla-inbound%20talos%20dromaeojs

you can see that the range is rougly 900-930 and after this push we go to 850-880:
https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?changeset=6cec52c43496

While the graph shows an improvement, it appears to be unrelated to any of these patches being backed out or followed up on.

as patch authors I have needinfo'd you to take a first pass and see if your patch could affect dromaeo dom (http://hg.mozilla.org/build/talos/file/tip/talos/page_load_test/dromaeo) numbers?

fyi, the improvement to this test is from this push (bug 1090398):

See https://bugzilla.mozilla.org/show_bug.cgi?id=1090398#c39 - I don't think this regression is real.

> fyi, the improvement to this test is from this push (bug 1090398):

It bug 1090398 affected the Dromaeo numbers legitimately, we seriously need to figure out a better test and retire Dromaeo.  Or something.

Likewise for the bugs in the regression range here... :(

Comment 6

[Michael Wu [:mwu]]

Bug 1085512 only affects B2G/Gonk.

Comment 7

[Kershaw Chang [:kershaw]]

Bug 1020186 only affetts to nsIOfflineCacheUpdateService, which I believe not used in Dromaeo test?

hmm, it seems as though this has magically corrected itself, this dromaeo dom test stuff has been really noisy lately.
