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.). > >In the mini market.

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. > Peter (Made in Australia) da Silva -- Stan uucp:{ihnp4!shell,rice}!neuro1!sob Opinions expressed Olan ARPA:sob@rice.arpa here are ONLY mine & Barber CIS:71565,623 BBS:(713)660-9262 noone else's.
