I leave swap on, but don't put it on SSD, and I don't do anything to
optimize it. To me, swap is like putting a 100 watt lightbulb in series
with an amplifier you're repairing. If you draw too much current (or
too much memory), it drastically decreases the voltage (or speed),
rather than burning up (crashing or killing procs).

When I see the machine slow way down, I look at virtual memory, and if
it's high I either:

1) Exit non-essential programs
2) Buy more RAM
3) Replace the offending program with a less piggy one.

I actually used #3 with Nautilus and with Kmail.
