Safari 3.0 is supposed to be much faster than its competition. Let's find out how tree that is.
Tests were conducted using a customized version of Sean Kane's JS benchmark. Each test was run 100 times on either a Mac G4 (1.5 Ghz) or Intel Pentium 4 (2.5 GHz). The tests were run with balanced browser restarts and computer restarts in order to cancel out any confounds, thus acquiring independent samples.
Overall Speed:
Safari 3.0 (Win): 398.6 ms
Safari 3.0 (Mac): 412.4 ms
OmniWeb 5.5.4 (Mac): 814 ms
Opera (Mac): 829 ms
Camino 1.5 (Mac): 1415.6 ms
Firefox 2.0 (Mac): 1755.8 ms
Firefox 2.0 (Win): 1768.6 ms
IE 7 (Win): 2101 ms
IE 6 (Win): 2109.2 ms
Safari 2.0 (Mac): 2727 ms

As you can see, it looks like Apple wasn't kidding us about the gains in Javascript speed with the release of Safari 3.0 for both Mac OS X and Windows XP/Vista. Especially, impressive is the work they've done on speeding things up compared to 2.0. Notice how Safari 3.0's total is less than some of the individual times!
While I was running these tests on another machine connected to the internet (not being used for testing), Safari 3.0 was noticeably snappier when visiting JS-intensive pages--I guess it wasn't my fan-boy bias after all. Good job, Steve.
Just a couple notes on some new features for us Mac users:
Command-Q asks before closing all of the windows open.
Because Command-W was only a key away from Command-Q, many times an accidental key press closed all open windows instead of the one intended. In terms of interface design, this was not good. The addition of the check makes me happy though.
History->Reopen Last Closed Window
History->Reopen All Windows From Last Session
Who wouldn't like these features!
One thing I'm wondering about is applescript hooks; I'll have to play with those later.
