Status: RESOLVED INCOMPLETE

Mac Tp took a terrible hit when Cairo was enabled.

Prior to Cairo-Cocoa in Firefox (21 Nov, 16:58), xserve06 was running between 177 and 179ms.  After Cairo-Cocoa, that jumped to between 302 and 309ms.  I used 178 and 306ms and got a 72% Tp regression if my math was correct.

Prior to Cairo-Cocoa in Camino (27 Nov, 12:24), pawn was running between 1101 and 1174ms :P  After Cairo-Cocoa, that jumped to between 1597 and 1663ms.  Using straight averages of all the collected values (1132 and 1619), that's a 43% Tp regression.

For maya, 357-364ms beforehand, and 480-543ms right after.  Using averages of 346 and 512ms, there's a 48% Tp regression.

Not sure why Fx was hit so much worse, other than that Camino's perf already sucked so much from all the trunk changes this summer....

I'm going through and marking old performance regression bugs as INCOMPLETE that are likely too old to be valid or get any traction on them.

Please re-open if you have more information or can demonstrate the regression still exists.
