(Although I just realized 1.9.2+madhatter won't be useful until bug 555885 is fixed.)
JFTR, Ts for Cm2.1-M1.9.2 is about 20-25ms faster than Cm2-M1.9 and 40-45ms faster than its direct counterpart, Cm2.1-M1.9, all on cb-x4. Cm2-M1.9: ~525ms Cm2.1-M1.9: ~545ms Cm2.1-M1.9.2: ~500ms (In other words, on our fastest Mac, we've made back the Ts regression from switching to Places [bug 553055] and then some, but that's not to say there's not more win to be had by actually investigating the slowness introduced by Places and other checkins and fixing/optimizing said code.)
Mentioning this here because there doesn't seem to have been a bug for it: after the cb-x1 rebuild (bug 513718, also tracked by Ts regression bug 458217) in September 2009, Ts slowly creeped up from about 520ms to 625ms over the course of about 3 months) on both branches. Last night I accidentally had two instances of tinderbox running, so I had to restart :( When cb-x1 came back on line, we'd dropped about 105ms from Ts time, to end up ~505ms on 2_0 branch and 517ms on 1.9.2. (I'll try to remember to keep an eye on it over the next few months and see if it starts creeping up again.)
(Also, this brings cb-x1's times back into the same range as those on cb-x4, although interestingly, 2.0.x is faster on cb-x1, but 2.1 is faster on cb-x4.)
