My experience, based on fairly heavy use of all three machines (and several others) but admittedly informal benchmarking (largely processor-intensive applications such as compilers and integer-computation tasks) would produce the following ranking: DS3100 = MacIIci < Sun SS1 = MacIIfx < HP9000/835 < DS5100 < Sun SS2. The SS2 is about 2x the SS1; the DS5100 is about 2x the DS3100. The DS3100 is probably 70-80% as fast as the fx, possibly less. I may be wrong about the relative position of the HP and the DS5100, but I think that's right... --John -------------------------------------------------------------------------- John L.
