The swap file is a vital component of the operating system and actually improves performance, not degrades it. The pagefile is used to store data in a contiguous file located on a hard drive. Data that is used less frequently or when swapped out from memory, it is stored in the swapfile. This means that when the OS needs data that doesn't reside in physical memory, it has to go to the disk. If the data was in memory once before, it would know exactly where to go in the swapfile to get it. If the swapfile isn't there, it has to find it again from somewhere on the disk. Also, Windows also uses a prefetch fucntion to actually forecast what files you need and puts it into the pagefile before the application actually requests it.Originally Posted by 'Falkor',index.php?page=Thread&postID=174335#post1 74335
If your're experiencing high disk activity there are things you can try to reduce it. First, disk drives with more buffer memory helps tons. Second, the faster the hard drive in terms of RPM is very helpful. 7200 RPM is the minimum for mutliboxing on a single system. 10K or even 15K is a huge performance boost. I am going to assume everyone that multiboxes on a single system maxes out their memory to 4gb or more (64bit) so I won't bother saying anything about memory qty.
As far as tweaking the pagefile, you can set the minimum and maximum swapfile size to 4096MB so it doesn't have to automatically adjust itself and you can put it on a separate drive from where the OS is running from. Also, defrag the drive where the swapfile is located often.
