I tend toward 2-3 times physical RAM for swap, as swap partitions, on
the following basis:
- Despite arguments that as memory increases, you no longer need as
much swap, my sense is that this is really a constant. Swap is
there for programs that are, er, swapped. Which isn't of itself a
bad thing. Swapping itself is what sucks, and if you're actively
paging in and out of memory constantly, you've got problems. So
the old 2-3x RAM rule of thumb holds, even as memory scales to the
GiB range.
- It's a lot easier to add memory than it is to repartition disk. So
if you give yourself two or three swap partitions, you can leave
one (or more) disabled until you max your RAM.
- Some level of disk optimization may occur by distributing your swap
across mutliple spindles. At the very least, put your first swap
partition on a fast, but underutilized, drive, if you have multiple
drives installed (I tend to put a swap with my /home partition).
Peace.
