|There are articles all over the internet written by people who have no idea of what they are talking about that recommend disabling the pagefile. The idea being that if you have sufficient RAM you should disable the pagefile because it is slower than RAM. This idea is based on a complete misunderstanding of how the pagefile is used.|
The pagefile was designed to optimize the use of RAM, however much you might have. It does this by offloading rarely used data to the pagefile, thus leaving more RAM available for more important uses. In the large majority of cases it works well.
Except for some very unusual situations the only advantage of disabling the pagefile is saving a small amount of disk space. With modern disk sizes this is quite insignificant.
Bottom line: unless you have a very specific reason, and you understand what you are doing, leave pagefile settings on default.
