Show me. I have yet to see ANYONE produce such results. I have run two
copies of what I use for benchmarks and in many cases, the VAX is still
slower.... Celerity is an excellant example. Of course, it should be 
realized that multiuser benchmarks are hard to do since the memory/swap
issue becomes very important when multiple invocations are concerned.
I am not sure that there is a good standrard metric for multiuser 
benchmarks that takes all these things into account (cache, memory,
swap, FPA, etc.).

Not many, but the real point is that you can buy a bunch of small computers
that run faster than a VAX for the price of a VAX. What is the difference
between 3 micros with 10 users each and one vax with 35 users? The cost and 
perfomance (higher throughput with the 3 computers) are the main ones.
