This article posted last week by Chris Martucci gives us 5 ways to make our Macs run more efficiently. Of course, he asks you to backup your Mac before doing any of the 5 tasks.
1. Delete Unnecessary Language Files (recommends Monolingual).
2. Run Maintenance Tools with Onyx (does maintenance tasks and deletes temporary items and more.)
3. Delete the Dashboard (Not sure that we gain much here).
4. Keep It Cool (temperature of the computer).
5. Tweak System Preferences (doesn’t require extra software).
The full article complete with details and links for the software listed above is available here: http://thisorthat.com/blog/5-easy-ways-to-optimize-your-mac
