speedin up the macbook

Over the last few months, I've been having a continual slow down on my mac book. Everything has been getting more and more sluggish, and slower to log in/shut down and even resolve dns addresses.

Over the last day or so, I've run a few things that seem to have it back to almost full speed again (yay!)

• Ran Leopard Cache cleaner, and did a few things including running most of the maintainence tasks - repairing
  
  
  permissions, the mac maintainence scripts, rebuilt prebindings, optimised system files (not sure if that helped or not), and did a medium level clean of local, system and user caches
• Repaired all my duplicate fonts, and removed a dodgy font (oh creampuff, I miss you!) - details on cleaning up fonts are down the end of this apple support discussion. No idea why that font was causing a problem, but it showed up as errored, so in the bin it went :(
• The usual hard drive cleanups - move off anything that can go to the network drive, ruthlessly kill junk from the downloads folder etc
• Got rid of a whole lot of stuff from my Quicksilver catalogs - probably doesn't affect startup/shutdown/login etc, but should help quicksilver in the future

Hope that helps anyone else that's suffering from a bit of a slowdown! Now to work out which of those tasks actually helped, and run it a bit more often.

(I'm running a Macbook 2nd(?) generation, Core 2 Duo 2GHz, OSX 10.5.3, 2GB Ram)
