Increasing Virtual Memory To Increase PC Perfomance

Are you tired from slow perfomance of your computer. Let's Talk About Some Ways To Increase Memory Perfomance. Although A Large Amount Of RAM Is desirable, it is not always possible to add more RAM to a system. Many applications require a large amount of memory to run effectively. To prevent applications from using all available RAM on a system and to keep memory efficient, the operating system will move less imporpatant data from physical memory (RAM) to a location on a hard disk to create virtual memory. You can modify how much computer virtual memory is available and how it's used to increase perfomance.

Processors are designed to guess what set of instructions or command are going to be run next and to load those commands prior to actully having to execute them. If a processors guesses wrong, a page fault occurs. A page fault is when the processor has to turn to another source to obtain the set of instructions, either RAM (which is very fast) or a paging file on hard drive (not as fast as RAM). Although a pafing file is not as fast as RAM,it is still much better than not having the command available, and so the paging file helps to increase the overall perfomance of the system.

To modify the computer virtual memory :

1. Click start ! Control Panel ! system to open the system properties.
2. Click on advanced tab and then click the settings button in the perfomance section.
3. Click the advanced tab and then click the change button in the virtual memory section
4. You will seethe virtual memory settings shown in figure :

Allocating Computer Virtual Memory
The amount of disk space allocated to teh paging file can be modified to increase perfomance. Basically, the more space allocated to the paging file, the more improvement in the perfomance. So what size should you set the paging file to? There are a number of answers to how long a paging file should be, and it often depends on the applications installed.The stock microsoft answer has been to set the paging file to 1.5 time the physical memory installed. So in a system with 1 GB of RAM, the paging file should be 1.5GB. Other publications recommend 2.5 times the physical memory installed. If exchange 2000 is installed, it recommends seeting the paging file to two times the physical memory installed.

Try setting the paging file to 0 or no paging file. Restart your computer and see what happens. If you have a large amount of memory (over 512MB) you probably won't see much of a drop in perfomance, as there is a plenty of RAM available for the applications running. The drawback is you will recieve periodic nag screens ( I mean, helpful Pop-ups) stating that you don't have enough virtual memory and so windows is creating a paging file for you.

If you make sure You have enough physical RAM to run things properly, the amount of virtual memory becomes secondary.And to answers the question about how large of a paging file to create: go with what you are comfortable with.The paging file should be at least the same size as the amount of physical RAM installed. Whatever size you decide,make sure that you set the initial size and maximum size of paging file to be the same. If the initial size and maximum size are diffrent (as the default) the paging file will constantly resize itself, which leads the paging file becoming fragmented and negatively affects perfomance . Whatever you do , do not allow the system to manage the paging file!

Note : After making changes to the paging file, you must restart the computer to commit the change.
