I am not quite sure about that: at 36GB RAM 99.9% of the [l][u|i]n[u|i]x out
there will not touch the swap, unless they really have to do, like in
specialized circumstances as such. If you have a 3TB smp machine, for
example, what do you use for swap?

Having said that, a neat idea I have been playing with includes a raid 10 on
4 intel SSDs, 160GB each, just for swap. The machine has 128GB RAM.
