The best way to improve system performance is to make better use of your RAM. Here are several hacks to show you how to try this before you buy more. No matter how much memory you have, you could always use more. Installing more RAM is generally the quickest way to better XP performance. But you can also speed up XP by making better use of the RAM you already have. In this hack, we'll look at how you can speed up your system performance by using your RAM more effectively.
Make Better Use of Your Memory with the Task Manager
it moves data and programs to a paging file on your hard disk, and your hard disk is slower than RAM. A certain amount of this is normal, but if you use a paging file too much, or if even your paging file can't handle the memory load, you'll run into system slowdowns and problems.
The Task Manager's Performance tab, provides the best way to monitor memory use. To run the Task Manager, press Ctrl-Alt-Delete, then click on the Performance tab. With it, you can interpret the information and make better use of your memory.
The charts relating to the Page File are self-explanatory; they show current usage, as well as usage over time. If you see that Page File use is frequently high, it means either that your system isn't making the most efficient use of RAM, or you need more RAM.
General Advice for Making Better Use of RAM
So, you've learned how to use the Task Manager. Here are some additional tips for making better use of your existing RAM:
Remove DLLs from cache memory. If you notice your system running slowly after XP has been running for some time, or if your RAM seems to be getting low for some reason, the culprit may be left-behind DLLs from programs that are no longer running, but that XP still keeps in memory. Sometimes XP keeps DLLs in cache memory even when the program that required them is no longer running, and this cuts down on the memory available to other applications.
You can use a simple Registry hack to have XP automatically remove from cache memory DLLs that are no longer needed by programs. Run the Registry Editor and go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ Windows\CurrentVersion\Explorer. Create a new DWORD value named AlwaysUnloadDll, and give it a data value of 1. Exit the Registry and reboot for the new setting to take effect. Note that this setting may cause problems with some programs. Some Windows programs—especially older and 16-bit programs—may issue error messages with this setting in effect; so if that starts happening, delete the new key or give it a value of 0.
Reduce the number of colors. Using 32-bit color takes up a great deal more memory than 16-bit color, and it also puts a greater strain on your processor. If you primarily use business applications such as word processors and spreadsheets, you most likely won't notice a different between 16-bit and 32-bit color, so going with 16-bit color is a good bet. To change your color depth, right-click on the desktop, choose Properties > Settings, and in the Color Quality box choose 16 bit.
Avoid DOS applications. DOS applications don't allow XP to manage memory properly, and they hold onto the memory they use, not allowing it to be swapped out for use for other programs or processes. If you use any DOS applications, replace them with Windows versions.
Reduce the icons on your desktop. Every icon on your desktop uses up memory. Delete icons you don't use regularly. Run the Clean Desktop Wizard, which will automatically delete icons that you don't regularly use. Right-click on the Desktop and choose Properties > Desktop > Customize Desktop > Clean Desktop Now. A wizard will step you through the process of deleting unused icons. If you want the wizard to run every 60 days, check "Run Desktop Wizard every 60 days."
Reduce the applications and services running in the background. You may have many programs and services running in the background, without realizing it. Look at your Notification area, and see if there are any programs running that you don't require. Shut them down, and make sure that they don't load at startup. For example, if you don't use a wireless network card, you don't need the Wireless Zero Configuration service.
