From: Rich Alderson <ALDERSON@SU-SIERRA.ARPA> I have before me a copy of National Semiconductor's publication "The NS16000 Benchmarks." They tested it out against a VAX 750 sometime prior to August, 1983 (the publication date). It out-performed the VAX on an FFT, and had comparable Whetstone times, when a 16081 (FPU slave processor) was attached. Before guessing any further about your own set up, I would note that the 32082 MMU (formerly the 16082) has in hardware both Page Referenced and Page Modified bits, allowing for LRU memory management. The VAX lacks the Page Referenced bit, and has to have same built into a table in the operating system. This slows it down badly. -------
