No hard data on hand, however a back of the envelope calculation
suggests that you probably have a good chunk of ram left - and that
this will probably expand if you can retire messages more quickly --
that has a tendency to speed up everything since everything has more
room etc.

I've never heard a bad experience with this approach, and I have
proven it several times on otherwise overwhelmed machines.
Paradoxically, for example, my woefully underpowered P2/450 will choke
if I don't run bind locally - even if the DNS server it points at is
on the a hot, dedicated box on the same switch. The minute I put bind
on the same box as the server it recovers nicely.

Understood. What about prescan?

Sounds good - I like Diskeeper too - won't run a Winx box without it.
