I just aquired a dual Alpha EV6 rack server, with two 667mhz cpus (4mb DDR cache each) on a UP2000+ motherboard. I've seen quite a few *nix variants that will run on this system, and I'm curious as to which will yeild the best performance with this type of SMP system. (I've only administrated x86 SMP servers to this point)
If anybody has some experience in this, their advice will be appreciated. It's a pretty non-standard archetecture, but when used at full potential it should be extremely fast. I'd hate to be held back by an OS that isn't optimized correctly to run with this hardware.
BTW: NT is NOT an option.
