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]. -Bob [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....
