Speed up Safari
This is a quick Terminal command that makes Safari appear faster by reducing the built-in rendering lag.
To try this (after backing-up, etc.) go to the terminal after Safari has quit and type:
defaults write com.apple.Safari WebKitInitialTimedLayoutDelay 0.25
The default time in the Safari preference time is 1.0. Now go ahead and launch Safari.
I just did this on the G5, and it seems to be making a big difference. Of course, it could also be all in my head.
