Using http://perf.snarkfest.net/compare-talos/ we can compare try talos to some m-c talos results. Use these changesets. original rev 48487f904abe a9b21fa2b7ab 3a8430b73a91 8fb3151c8db4 new revision f9eb580dd56b new revision 05a791444e43 origina rev a75699fa48e3 3d4ba021c4dd 55953a91b4d6 f001894b50ea 9480e51be5b7 Some wins, some loses, some things look broken.

I guess Tp4 still needs investigation. Tp4_xres on Linux-32 too. Maybe the latter one would be easier to figure out and give us wins on other platforms if we can fix it.

Tp4_xres on linux 32 is in bytes, so it goes from ~700 bytes to ~2000 bytes. For comparison Tp4_xres on linux 64 is ~13 MB. I compared a build with and without 130078 (not based on the same revision, but fairly close) on linux 64 and the build with 130078 was 1MB smaller. That was only one run, so I don't know if that's enough to see whats going on. Tp4 on mac (32bit) and winxp are the ones that seem to show a regression. All other platforms seem to show an improvement or within the normal bounds.

Discussed linux Tp4_xres numbers on irc with roc and Karl. We concluded there is no way the 32 bit numbers can represent anything meaningful.

As discussed on IRC, paint suppression is likely to be an issue here for the Tp4 numbers.

These are numbers when we restore paint suppression to the root content document (and all subdocuments).

The automated talos scripts flagged the Tp4 Xres increase and the mac Tp4 increase.

Bug 591435 landed and turned all Tp4 results into mostly wins, and a few no change from per 130078. Calling this resolved.
