If so, it could well be that OSX isn't having the opportunity to perform daily/weekly/monthly maintenence. This can often seriously slow things down after many missed maintenence tasks. Follow the instructions in the AppleCareKnowledge Base document "Mac OS X: How to Force Background Maintenance Tasks (Logs and Temporary Items)" <http://docs.info.apple.com/article.html?artnum=107388> to manually run these maintenance scripts. You might also check Activity Monitor to see if there's not some rogue process unnecessarily draining CPU cycles. Also go through the standard troubleshooting tasks - boot from the OSX install disc, run Disk Utility to repair disks, repair permissions, then run Techtool and/or DiskWarrior through it's paces. As Techtool is still within it's support contract you might try seeing what MicroMat has to say about this slowness. Some disk utilities automatic tests running in the background can slow things down. Regards, Jamie Kahn Genet -- If you're not part of the solution, you're part of the precipitate.
