No, it'd be a *huge* performance incrase. The trick with the disk
IO is to have an efficient filesystem. We still haven't got one yet.

To see what I mean, use the "null" filesystem, and run a polygraph-3
test on it. You'll note how it'll top out around 300 req/sec.
If squid was SMPed, you could probably get between 500-600 req/sec
on two CPUs. You just can't do that yet for various reasons.
(Well, you could, but the squids would be totally seperate from each
other, which for most people isn't very useful, but it *could*
be useful to some..)

Its being worked on. But, as people are probably aware, squid is now
pretty much fully-volunteer driven, and so we don't get to spend as
much time on it as we'd like.
