The magic amount of swap is the totaly memory you ever expect to need, minus the amount of physical RAM you have. That's it, really. These 1xRAM, 2xRAM, etc. rules are just vague hand-wavey guidelines. Just guess how much memory you might need and subtract 1G (in your case).
Note: some systems mirror the physical RAM in swap, so having less swap than RAM is meaningless and having the same amount is pointless. Linux doesn't do that, so the amount of swap you allocate is added to your total RAM available. Greg ----------- "With sufficient thrust, pigs fly just fine.
