please don't flame me, i know this topic has been beaten like a redheaded stepchild but i still have a question... i have 384megs of ram so after reading all the posts i figured a fixed 256meg swapfile should be fine. to test this, i set the swapfile size and opened photoshop and increased an image to a size of 639megs, while the picture was open i did some flask encoding at the highest settings, to top it off i watched a bit of a high bitrate divx movie. during all this according norton system doctor my max swapfile usage was 75%. now, i probably answered my own question but is there anything else i can run to make sure i have set the swapfile big enough? i don't want to be in the middle of something important and get an out of memory error message...
