I found a PowerMac 7500/100 (PPC 601) to be the same overall speed as a
Sun SPARCStation 10/51. This was also the same speed as a Pentium 90
running Windows 95. The Pentium had a Matrox video board that was 3x
faster than the Vitek video board on the Sun, and about 4x faster than the
built-in Mac video. Unfortunately, these are all 3-year old systems now.
I'd like to see additional comments regarding newer systems.
My feeling is that the Sun would begin to outperform the PC and Mac
hardware when all of the systems are under higher loads. Generally
speaking, UNIX systems are geared for handling hundreds of queued
processes, whereas the other OS's degrade faster under higher loads.
