To speed up the interface on any intel mac, boot in single user mode (command 's' at start up), and type "exit". It is going to take all the base Apple drivers delete them, and then reload them. It will then load into Tiger. Just make sure you restart from there and everything will be back to normal and hopefully faster. It did wonder from my 2.33GHz C2D, and all my Co-Workers MacBook Pros. It works amazingly well for some machines, and makes no difference for other machines.
P.S. Please do not try this if you are not comfortable in Single User Mode.
