From Talos emails: Regression: Mozilla-Inbound-Non-PGO - TResize - WINNT 5.1 (ix) - 8.51% increase ------------------------------------------------------------------------------- Previous: avg 12.915 stddev 0.205 of 12 runs up to revision cbe9a2aea954 New : avg 14.014 stddev 0.231 of 12 runs since revision 5ddf0a252b08 Change : +1.100 (8.51% / z=5.365) Graph : http://mzl.la/1CxCMlK * http://bugzilla.mozilla.org/show_bug.cgi?id=1162824 - Change box shadow cache to cache the colored blurred box shadow * http://bugzilla.mozilla.org/show_bug.cgi?id=1169044 - Fetch uses wrong referrer * http://bugzilla.mozilla.org/show_bug.cgi?id=1175556 - ARM64: Land final, miscellaneous changes * http://bugzilla.mozilla.org/show_bug.cgi?id=1155828 - Speed up box-shadow drawing by using a border-image style This is caused by me, in bug 1155828. This is caused because we call FillRect at [1], on a cairo backend on Windows XP. See [2]. We're ok accepting this regression. On real web pages that use box shadows, we can get up to a 25x improvement. See [3] and [4].
