Hi John, quick and short: don't run Unix or Linux system for that matter without a swap partition. Yes you can do it with a file but it's not efficient. You are going to have extreme problems if the system runs out of swap or if there is none when you load a lot of applications or services in your system. General rules are to use swap big as 2 to 5 times RAM. In your case with 512MB of memory I would suggest between 512MB and 1GB. Since you most likely won't use graphics on your system, 512MB should be enough. I have 1GB of swap, 1GB of RM on 2CPU Pentium system at work and KDE with 10 virtual screens on desktop which is just about right. Swap is more efficient if you put it on another disk drive. Old drives are fine since you don't need to worry about data on them. On Tue, Oct 05, 2004 at 09:24:12AM -0500, John J.
