It's not too old, and I would recommend that you give 7.0 a try. Don't forget to enable the ULE scheduler. I've got a dual Celeron-466 with 448 MB RAM, and it's certainly not too old, either. (OK, Celerons aren't the best processor to build an SMP system, but it does work nicely for me. And it was dead cheap for an SMP system at the time when I built it, about 10 years ago.) > My hacked up 386 showed gains going from 6.2 to 7, the big win that I've > noticed is scp throughput, I can sustain 40 to 45kbps where in the past > the box walled at around 30kbps.

Are you saying you run FreeBSD 7 on an 80386(SX/DX) machine? How exactly did you hack it? As far as I know, support for 80386 processors was removed from FreeBSD a while ago.
