Only if there are better things you can do with that disk (or money.)
In this case, RAM might be a better priority, see below.

We made the mistake however of just allocating 512MB swap as we did not
know accurately at the time of installation what the resouce requires are
going to be (especially not that it would be this high).
A traditional rule of thumb is to have 1x - 2x the total RAM size in
swap space. This assures
Actually having a separated disk for swap should increase your performance.
But my opinion is that if you really need *all* the 40 GB of swap when your
system's ram is 3 GB, you won't see the difference: most of the data your
system needs is swapped out!
You could add a partition to your new

Jamie,
Run the following script on your system under maximum load.

awk '{
i += $1;
j += $2;

If you see VSZ is very close to the swap size and RSS is getting
closer to the available physical

From what I've read, x86 can address 4 Gb of memory,
