Safari has a huge memory leak that causes it to create excessive swap files if it remains running for a long period of time; quitting and restarting it a few times a day will help, though you have to leave it down for a few minutes so swap files refresh. If you don't leave your computer on over night, download an app via versiontracker called MacJanitor and run the monthly, weekly and daily tasks that Unix normally does at 3 a.m. If these files are not cleaned up occasionally. you will see a decrease in performance. -mike
