me and jbone were jsut discussing this last night as i was having some virtual memory issues. first of all.??.if you use premire, use all the swap space you can.???.in win2k, which i use you can set your limit to 4045 MB i believe. I keep my lower limt at 768MB. I don't have a shabby comp. I got a 1.33ghz athlon with 512 mb of 2100 DDR memory and a 180 GB stripped RAID array and a 30 GB 7200 ATA 100 drive for system stuff. When working with VOB's and each one is hitting a gig a piece, what virtual memory will allow for you is to open a few clips at a time and not have your system laugh at you or perform verry slow. Since with VOB editing you are running a frame server, it helps to be able to cache all the information related to frame positions and so forth with your virtual memory which is nice when you are working from a few different episodes, same goes with normal editing if you are working with large clips, as i will cache a lot of that inofmation so it doesn't have to re-determine it such as location of keyframes etc. The larger the swap file, the more information you can store and not have to throw out. Every programer knows that it is much easier to read information instead of derive it every time you want to use it. That is what virtual memory is used for. Even though it is slower than RAM by a whole lot, it is quicker than trying to use system resources to redetermine information that is allready in your swap file on your hard drive. When editing, you really should be using two hard drives anyway, one for system so you can allocate more swap space and not have the hard drive that you are using to read or capture your clips from being accessed by the system while you are trying to capture or just read the video files from. This might not matter when you are using smaller files sizes, but when you are working with large files it helps a whole lot. For optimal swap performance, you should have your swap file on a HD that isn't being used for system or storage of the clips you will be using. But it never hurts to have a large swap file. It all really depends on the type of demands you are putting on your system weather having a large swap file will actually make a difference to you.
