However, there are still some PCI bus problems on the PPro (actually the Natoma/Orion chipsets.) I think that if you are "pushing" the PCI bus, the Triton-II on a P5 will do you better. Compile times, etc. are better on a P6, and SMP will work much better. > > Some insight would be appreciated. > The 2.1.X series hasn't had serious VM work done on in in about 1-2yrs. It performs okay, but is about 1 generation behind. The 2.2 series is much better and has some improvements for PPros. (Global TLB bits, use of bswap, etc...) 2.2 will also work better on large systems. John
