Re: virtual memory not taken into account
Some other swap tips:
Making changes to swap settings do not require a reboot. Just type this in a terminal window:
sudo swapoff -a && sudo swapon -a
To verify your swap is on:
swapon -s
If you have more than on hard drive, you can set up a RAID-like swap file by using multiple partitions on all your drives and giving them equal priority in /etc/fstab. My swap portion of fstab looks like this:
Somewhat old school notions but likely still true:
Swap space is slightly faster as partition 1
Swap space should at least equal your RAM size
However, I believe this last one is a rather simplistic view. If you hibernate, I agree. If you don't use hibernate, unlikely you will ever need 12gb of swap if you have 12gb of RAM. I have 8gb on my desktop and I've never swapped to RAM that I am aware of.
