Where do you see it "recommended"? In ancient times (before Linux) there was a rule of thumb that swap should be 2x physical memory or at least a bit more then 1x for Unix systems. There were 2 reasons for that as I understand. 1) an artifact of how the swapping code worked. 2) so there was sufficient space for all of memory in the event of a panic (which wrote all of memory to the swap device, which Linux doesn't do). Nowadays with memory speeds so much greater the disk speeds, having a huge amount of swap for most workloads doesn't really help. If you are using that much swap, your performance is really going to suck. Just get more memory. -- Kernelnewbies: Help each other learn about the Linux kernel.
