AFAIK so far, the 200 MHz PPro is still the CPU to beat for servers. Some well-behaved (cache-wise) jobs see very significant improvements on PII's, especially 300 MHz, as will anything using MMX. But for servers, a 440FX-based dual PPro 200 still looks best as far as I can tell. Actually, there are more expensive motherboards that can perform better, (e.g. Corollary, HP, etc.) but, they are *much* more expensive. For this market niche, I would thing Natoma-based ASUS, SuperMicro, etc. would be appropriate. In any case, it would be nice if folks with FreeBSD -SMP running could start posting results. For a server, the best test might be something like "make -j16 world". |> On Thu, 9 Oct 1997, Andrzej Bialecki wrote: |> > * ASUS m/b has on-board NCR SCSI. Should I use it, or go for 2940UW? I'm not sure which NCR this is, but, my experience with ASUS NCR-based controllers has been good. YMMV. Adaptecs can be expensive. |> > * What processor/bus speed (I'll be very hungry for PCI bandwidth)? I was hoping someone would answer this. I have seen incredibly diverse and conflicting information about the PCI performance on various chipsets/motherboards. Does anyone know of some recommended web pages, etc. on PCI performance? -Hugh LaMaster
