I'd say, if a system has more swap space than memory space, it can use
swap in a different way (using different algorithm) that will speed up
things a little bit. BUT using swap this way would slow things up if you
have less swap than memory.

linux kernels 2.4 under 2.4.10 had a problem that caused very low
performance if you had less swap than 2xRAM (I don't know if it was
because of problem I described above)

However having enough memory will speed up things much more

However this discussion is not related to squid, so let's say the old
good: on a system with squid, you should have enough memory not to swap at
