Optimal Level
I always really like to keep my Mac running at an optimal level. There is nothing more frustrating for me than when my Mac slows down or just runs slower than what I am expecting. I recently was doing some shopping on the Internet for a Car Loan and my computer completely locked up while I was putting in some very sensitive financial information. That really concerned me because I was not sure what happened and what could have happened to all of my sensitive data. I took my Mac to a friend and he is working on it to get it back to working like it did when it was new.
