IJ Reilly said:I've never heard this rule of thumb before. Even if it were true that 5-6 Gb of disk space was required for virtual memory, then it certainly would not matter if that 5-6 Gb amounted to 1% or 10% or 50% of the maximum drive capacity. As one who monitors his VM swap files, I can say from experience that it's rare for them to take up more than 2 Gb, and they can be made to go away with rebooting.
Yeah, I sort of suspect that the rule of thumb was probably intended only to apply to smaller drives, but someone who knows more about this can maybe fill us in on that.
At any rate, the VM on my 12" PB is currently at 4.98 GB.
