One thing I have found quite useful is compcache. This allows you to
use compressed ram a swap-device. It doesn't need a physical disk and
has zero latency so it avoids many of the disadvantages of physical
swap devices. It tends to give a 4:1 compression ratio, though I
wouldn't recommend a compressed ram swap device much larger than 50%
of ram or so.
