You're welcome, but now you have to upgrade it, because beta 11 is out 
This version turns on JavaScript acceleration for everybody, even G5 users. G5 users will see less improvement, but will still see some. G4 and G3 owners will see the most improvement. There are also some bug fixes and the browser is overall quicker thanks to rendering improvements.
Just for yuks, I put a chart on the main page of a browser JavaScript speed comparison I did when I was at my folks' last (see above) since Dad runs 10.5.8 on his G4 mini so that he can use iTunes 10 (I'm the Nexus One heathen, my folks use their iPhone 3GSes still). This gave me a chance to test Safari 5. No points for guessing that TenFourFox won by a large margin, but I think people will be very surprised by which browser came in 2nd. I didn't expect this either.
