No matter how diligently you perform the maintenance tasks in thisbook, you wont truly know how well (or how poorly) your Mac is running unless you make the effort to find out. The fact that no smoke is billowing from your SuperDrive is a good sign, of course, but its hardly definitive proof that all is well. In this chapter, I show you how to find out whats going on under the hood.
Numerous utilities (most of them free) can provide up-to-the-minute statistics about your Mac. In most cases, these programs run in the background all the time, but if you prefer, you can run them manually when you get curious about your Macs current state. I provide a list ofseveral such utilities just ahead (see Monitoring Utilities ). But first, you should understand what data you might want to monitor and why.
Mac OS X usually manages your computers RAM efficiently for the most part. Applications can dynamically adjust the amount of memory they use, and even if all your RAM is actively in use, a virtual memory system lets Mac OS X use a portion of your hard disk to extend your RAM, automatically swapping (or paging) data between the disk and the physical RAM as needed. Even so, if you have enough applications open at once, and if they require enough memory to perform their respective tasks, you can reach a point where data swapping occurs constantly. This slows everything way down, and it uses disk space.See All
