I've been using SMP on my P2 450mhz tyan thunder 100 motherboard for years now. RH5.x (currently on 7.3). As time has gone on, it's got better and better. I think my uptime is somewhere over 30 days currently (I have power issues where I live, otherwise it would be much higher). It runs 2 seti processes, and is my samba server for my windoze machines. Also does my rsync'ing stuff for my empegs.

I'd love to have a 4/8 way system to try it on. Oh to dream
