The old rule-of-thumb was swap should be twice your RAM size. I still adhere to that, however if you ever get to the point where that's becoming an issue, you have other problems and performance will suffer. > > That said, on my laptop I have 1.25 G ram with 1G swap (originally I had 512M > ram but upgrade a year back, and didn't increase the swap size as I cannot > easily repartition) . Did you ever think about adding a swap _file_? It's easily done. > However, I have never run into problems with > hibernation failing because of this - most of the time hibernation only uses > 200-400M, a small fraction of the available 1G swap. Yes, actually hibernation will only use the amount of swap necessary to save the active RAM contents (essentially, all of your active stuff gets swapped out). ---------------------------------------------------------------------- - Rick Stevens, Senior Systems Engineer rstevens@xxxxxxxxxxxxxxx - - VitalStream, Inc. http://www.vitalstream.com - - - - You know you've landed gear-up when it takes full power to taxi. - - -- Chuck Yeager - ----------------------------------------------------------------------
