Current trunk is more than 20% faster on Mac and Linux Twinopen[1][2].  On XP, trunk is about 15% slower[3].  On Vista, there appears to be approximate parity[4], but this is confounded by bug 419620.

2/3 ain't bad, need to figure out what we can still do on WinXP, but we're in pretty good shape at this point.

stats as of last night:

WinXP is currently 3% slower than Fx2, which is a minor regression (we were about 1% faster after PGO)
Linux: 35% faster (Woo!)
Mac: 21% faster

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.
