Here's some hard data, not what you want maybe, bue anyway: I compared a large number of systems, including: Microvax 3200 with the ninth edition unix. (this is more or less the same then the vaxstation 3100) Sun 3/80 with Sun OS 4.0.3. Let me only give you some cpu results as system calls and disk-related stuff is too OS specific: test Sun 3/80 Microvax 3200 sieve 5.1 4.9 sine 10.1 6.0 loop 10.9 11.0 So I would say that they are a pretty close match, except for floating point where the Microvax excells. (yes, the 3/80 was using the fp chip).

Thus, your 3200 numbers timings should be divided by 0.89. That makes integer stuff slightly slower than the 3/80, but FP calculations still look significantly faster.

Does anyone have any hard data comparing the VAXstation 3100 (running Ultrix) against the SUN 3/80? SUN is claiming the performance is the same as the VAXstation 3100 but I don't have a 3/80 to compare against our VAXstation. If anyone has done any benchmarks between these two systems I would appreciate any data you may have gathered. -- David White Grass Valley Group, Inc. VOICE: +1 916.478.3052 P.O.
