i've never been fond of the Mac look, but it is blisteringly quick.
honestly i think they have their times wrong:
on here -
Explorer 7 (apple.com) 2.8s
Safari (apple.com) <1s
FireFox 2 (apple.com) 3.8s
that's for the entire page to load. Explorer will show the topbar in <1s but the rest of the page then takes a couple more seconds to finish loading. This said explorer loads all of the page before rendering rather than just what you can see; not sure if safari is doing the same though.
not sure about javascript as i didn't bother testing it, but still quite impressive.
this said new windows loading times are quite different.
(from cold boot)
Explorer 7 - 4.1s
Safari - 15s
FireFox 2 - 12s
(from pre-load boot)
Explorer 7 - <1s
Safari - 4.3s
FireFox 2 - 8s
Also the Memory useage is quite crazy:
Explorer 7 - 8MB (plus 4MB for ieuser)
Safari - 26MB
FireFox 2 - 24MB
although this said Safari won't expand exponencially like FireFox 2 does by simply browsing, or atleast hasn't on me yet.
also Safari seems to be very memory concious:
6 tabs (apple.com)
Explorer 7 - 26MB
Safari - 32MB
FireFox 2 - 72MB
will stick to Explorer 7 though, as i prefer it.
