This opens the System Properties dialog box with the Advanced tab displayed. Select Start, type advanced system, and then press Enter to select View Advanced System Settings in the search results. This is the default in Windows 7, but it's worth your time to make sure that this default configuration is still the case on your system. Optimizing programs means configuring Windows 7 so that it gives more CPU time to your programs. In particular, processor scheduling differentiates between the foreground program (the program in which you are currently working) and background programs (programs that perform tasks, such as printing or backing up, while you work in another program). This involves adjusting the processor scheduling, which determines how much time the processor allocates to the computer's activities. You can set up Windows 7 so that it's optimized to run programs. I show you how to update device drivers in Chapter 22. In general, the newer the driver, the faster its performance. If your application works with a device, check with the manufacturer or Windows Update to see whether a newer version of the device driver is available. It probably won't make much difference, but experiment with setting the Registry's EnablePrefetcher and EnableSuperfetch values to 1 to optimize application launching. (See "Examining Hard Drive Performance Specifications" later in this chapter.) This enables Windows 7 to access the application's data and documents faster.Īs I mentioned earlier in this chapter (see "Configuring the Prefetcher"), Windows 7's fetching components can optimize disk files for booting, application launching, or both. If your system has multiple hard drives that have different performance ratings, install your applications on the fastest drive. If the amount of available memory starts to get low, you should consider adding RAM to your system.
Task Manager-Display the Performance tab and watch the Physical Memory: Available value. Use one of the following Windows 7 monitoring tools to watch the available memory value: Author Paul McFedries introduces new styles and techniques to maximize your Windows 7 performance.Īll applications run in RAM, of course, so the more RAM you have, the less likely it is that Windows 7 will have to store excess program or document data in the page file on the hard disk, which is a real performance killer.
This book goes deep into Windows 7 and covers everything from security settings to startup optimization and networking. This chapter excerpt on Tuning Windows 7's Performance (download PDF) is taken from the book Microsoft Windows 7 Unleashed.
