Download free Tuning Windows 7 Performance guide.pdf We often wonder why our workaday computer chores seem to take just as long as they ever did, despite the fact that hardware is generally more reliable and more powerful than ever. The answer to this apparent riddle comes in the form of McFedries’ law of computing codependence: The increase in software system requirements is directly proportional to the increase in hardware system capabilities. For example, imagine that a slick new chip is released that promises a 10% speed boost; software designers, seeing the new chip gain wide acceptance, add 10% more features to their already bloated code to take advantage of the higher performance level. Then another new chip is released, followed by another software upgrade—and the cycle continues ad nauseum as these twin engines of computer progress lurch codependently into the future.

So, how do you break out of the performance deadlock created by the immovable object of software code bloat meeting the irresistible force of hardware advancement? By optimizing your system to minimize the effects of overgrown applications and to maximize the native capabilities of your hardware. Of course, it helps if your operating system gives you a good set of tools to improve and monitor performance, diagnose problems, and keep your data safe. Windows XP came with a decent set of client tools, Vista improved on them (although not with anything radically new or earth shattering), and Windows 7 stays the course.

Performance optimization is a bit of a black art in that every user has different needs, every configuration has different operating parameters, and every system can react in a unique and unpredictable way to performance tweaks. That means if you want to optimize your system, you have to get to know how it works, what it needs, and how it reacts to changes. You can do this by just using the system and paying attention to how things look and feel, but a more rigorous approach is often called for. To that end, the next few sections take you on a brief tour of Windows 7’s performance monitoring capabilities.
