A small collection of performance hints
The amount of RAM you have will not materially affect your CPU usage. CPU usage should be in the single or low double digits if the system is idling with no open apps. To fix this, open the Terminal and type "top -u" (no quotes of course). This orders the results in decreasing CPU %. Watch this for awhile and see 1) what the split between system CPU usage and user CPU usage is and 2) what things are at the top (no pun intended) of the list when CPU is spiked. I'm betting you have one thing that is behaving badly. Rememeber that top itself sucks up andf 10% of CPU so use it sparingly...

You can make top suck less by adding '-s 10' to mean poll every 10 seconds instead of the default 2. Also, hitting space while in top will cause it to update immediately. |
