Here's the perf-o-matic graph of the last 365 days of talos history for 'SVG, Opacity Row Major':

Select the regression in August and you'll see that on August 13th:

MacOSX 10.7 regressed 418.6%
MacOSX 10.6 regressed 351.2%
WINNT 5.1 regressed 242.4%
WINNT 6.1 regressed 42.1%

The pushlog for the regression range is:

Seems like one of Matt's bugs (bug 539356, bug 770000, bug 733323, bug 781362 or bug 780868) is guilty of the perf regression.

Note that on October 10/11 and on Nov 6 we gained back some of the lost ground (except on WINNT 6.1), but we're still not close to being back to where we were. It's also not clear that either of those gains were due to partially fixing the regression that resulted in this bug.

Pushlog for October gain:

Pushlog for November gain:

Is the regression still there?
