Generally speaking, mail and file server are not RAM intensive. A 32 proc can directly address 4GB RAM (2**32). FreeBSD allows you to address more than 4GB on a 32 bit proc but limited to 4GB max per process. The actual per process limit will be a bit less, I think. A 64 bit proc can

2006-08-25 Thread Martin Miedema
I hope that I'm not starting some sort of holy war with this question, but here I'll go. I'm planning to set-up some e-mail / file servers running FreeBSD 6.1 in the near future and I'm wondering if it will be worth the cost to use 64 but CPU's for this. Also I would like to know which
