I'm concerned that Bug 67876 has been unresolved for upwards of a month. It's important that we not carry these regression in the tree because they mask other regressions. Do you have an estimate for when this issue will be resolved? 477005 5 reed 2011-10-03 08:56:31 -0700 Should be fixed in latest skia DEPS roll. 477010 6 abarth 2011-10-03 09:06:33 -0700 > Should be fixed in latest skia DEPS roll. Thanks Mike. It looks on this graph that we've gotten most (if not all) of the performance back: http://build.chromium.org/f/chromium/perf/xp-release-dual-core/intl1/report.html?history=150&rev=103710 This improvement appears to have been cause by rolling Skia: http://src.chromium.org/viewvc/chrome?view=rev&revision=103704 Just to confirm before closing this bug: That improvement is the fix for the Sept 28 regression and not for the regression we're tracking in Bug 67876 ? (They are of a similar magnitude, which makes it hard for me to tell just from the graph.) 477011 7 reed 2011-10-03 09:10:15 -0700 I think so. The recent regression was definitely due to 2358, which was (effectively) reverted. 477014 8 abarth 2011-10-03 09:12:30 -0700 Thanks for the quick response.
