HorseCookies. Think about it. The slowest ram on earth [1]
runs rings around the fastest raid stuff you can find. Disk is
slower than memory. If you're I/O bound *and not memory bound*
crank up bufcachepct. The *and not memory bound* is the part
I meant about "not doing anything else" - because I know you're
not going to be memory bound running spamd [2].

[1] Please don't try to find me ram as slow as your disk. I don't
want to know :)
[2] assuming you're running a machine from the century of the fruit bat.
Yes, you can be memory bound running spamd on a 12 megabyte cyrix 386 or
something like that....
