A few years ago the general rule of thumb for swapping was swap=RAMx2.
Now that seems fairly sensible when ram was smaller than it is today. My new rig arrives tomorrow and with 8gig of ram following the rule of thumb above would mean 16Gig of swap space.
Now with larger disks as well 16Gig of spaces isn't as big as it used to be, but it still seems a smite excessive.
So my question is at what point does a swap partition become unnecessary. I would say that with 8Gig I am rarely going to hammering the memory so hard as to use it all up.
Is a better option to have no swap partition at all and setup swap files as and when you know you are going to be running memory intesive applications? Or perhaps still have the swap partition, but maybe a different ratio such as swap=RAM or swap=RAM/2?
Id appreciate anyones thoughts.
