Test done with Dronaeo website (a collection of some JS benchmark script done by Mozilla foundation) on a 2.4GHz Macbook w/ 4GB of RAM.
Windows Vista SP1 (virtualized in Parallels)

Google Chrome pwns all… it’s the 1st column, wrongly reported by dromaeo test as “Safari/525.13“. Firefox 3.01 is four time slower, and Opera 9.51 and Safari 3.2.1 for Windows (reported as “Safari/525.21“) are closer. And oh, IE simply crashed running the page ;(
Mac OS X 10.5.3 Leopard

Firefox 3.0.1 wins, but Safari 3.2 made very similar points… Opera is a bit slower than in the windows counterpart… (Good ‘ol) SeaMonkey and Shiira (reported as “Firefox/2.0.0.16″) are four times slower…
Linux Kubuntu64-current:

Galeon (linux only) is the fastest browser after Chrome, but Firefox 3.0.1 is very near. Konqueror 4.1.1 and Opera 9.52 make decent figures, SeaMonker as usual is the last ;D
Now some inter-OS speed comparison:
Firefox 3.0.1: http://dromaeo.com/?id=28106,28286,28540
measured exactly the same speed on ALL os!
Opera 9.52: http://dromaeo.com/?id=28169,29286,28303
is a lot faster on Windows than Linux or OS X.
Seamonkey 1.1.11: http://dromaeo.com/?id=27933,28439,29213
is slightly faster on Linux than Windows or OS X.
EDIT: Google Chrome vs all memory usage screenshot here.
