When your Mac slows down, productivity suffers. Here are five easy ways, and a few of their friends, to speed up your Mac. All are free and will take very little time to implement.
1. Quit Unneeded Apps, Close Unneeded Browser Windows/Tabs — The quickest and easiest thing you can do to improve your Mac’s performance right now is to quit unneeded apps and close browser windows/tabs — nothing sucks life out of a Mac like a seemingly innocuous bit of Flash running, out of sight in a browser tab!
— Don’t want to lose/forget those webpages? Bookmark (Command + D) or Add to Reading List (Command + Shift + D) to save
— Check out ClickToFlash, a highly effective Flash blocker that feature whitelisting
2. Restart Your Mac — For a fresh clean restart, quit all apps and then select Restart from the Apple Menu.
3. Clean Up Your Desktop! — Have more than a few files and/or folders on your Desktop? This can slow your Mac down, big time. Clean up that mess and store files, etc. in the Documents, Music, Movies, etc folders in your Home directory.
4. Repair Permissions — Just using your Mac can result in things getting turned around a bit. When permissions get mixed up, your Mac slows down.
— Open Disk Utility: Macintosh HD > Applications > Utilities > Disk Utility
— Select Macintosh HD and click Repair Disk Permissions
— After Disk Utility is finished, click Verify Disk Permissions to insure that the job got done. If not, run Repair again.
5. Quit Unused Dashboard Widgets — Many users don’t use the Dashboard, so why not either turn off the widgets you don’t use or even completely quit the Dashboard?
— Open Dashboard and, while holding the Option key, mouse over the Widget you’d like to close and click the “X”

Still not fast enough? Far and away the most effective way to speed up your Mac is more RAM — perhaps you do not have enough. To check how much memory your Mac has, go to the Apple Menu and select About This Mac.
Although 2GB RAM is the minimum requirement for Macs running OS X 10.6.x or later, 4GB is considered more practical and, as always, more RAM is always better.
