Since memory isn't very expensive these days, I'm thinking of adding more RAM to my FreeBSD machine; it has 256 MB, but I was thinking of going to 1 GB, which is the capacity of this machine. Currently, I have a 800 MB swap partition (or is it a slice?--I know it's not a filesystem) defined. Is this enough for 1 GB of RAM? Is there any kind of strong correlation between RAM size and swap file size that I have to be concerned about? Does FreeBSD resort to swap only when RAM is exhausted, or does it have to use the swap file all the time (as in a one-to-one VM mapping scheme)? If the swap file is of less than optimal size, what happens? I looked at the swapinfo command and it shows 0% of the swap file used (the system is not heavily loaded by any measure).
