There are lots of theories about how big to make your swap partition (or partitions -- you can have more than one) Some people say two times the size of RAM but most don't give any reason why that particular multiplier. There is logic for having at least as much swap as you have RAM (in other words, a multiplier of 1.0) because, when the system panics, it may want to make a copy of RAM to the swap space for later analysis. This logic makes most sense if you're in a development shop where analyzing core dumps is a common practice; most folks aren't in that situation. For modern machines, it's possible (and even common) to have enough RAM that you never need to swap at all, so a multiplier of zero is reasonable. But there are uses for swap space that have nothing to do with swapping programs in and out of memory: For example, if you decide to put /tmp in a ramdisk, you may want to allocate a swap partition that's much larger than your RAM as backup in case somebody needs *lots* of space in /tmp. This will allow the system to use RAM for /tmp when the demand is light, and back-up to swap disk when demand is heavy. So the definitive answer is, "It depends". Your expected usage will determine how much swap space you need. My personal rule of thumb is, "Start with twice your RAM and adjust from there depending on experience." Does that help?
