With a whole lot of help from my friends (dbaron, mcafee, and jrgm to 
name a few), I've managed to get a tinderbox running a ``loopback'' 
version of jrgm's Performance Tests (tm); it's ``btek'' and is currently 
on the SeaMonkey-Ports page,

   <http://tinderbox.mozilla.org/showbuilds.cgi?tree=SeaMonkey-Ports>

It's doing an optimized, depend, browser-only, Linux build (to turn 
around quickly), and then running jrgm's test harness to a webserver 
installed on the same machine (to hopefully eliminate as much noise as 
possible). It is reporting jrgm's ``average page load time'', and 
appears to be fairly stable -- i.e., typically varying less than 1% from 
run to run. The tinderbox log contains the detailed output of the 
performance test (i.e., the individual page load times).

All ye lovers of layout, keep an eye on this tinderbox: I hope that it 
will allow us to catch performance regressions much more quickly 
(because we can narrow the Window of Shame to an hour's worth of 
checkins, instead of a day's worth).
