Re: [Simh] EXT :Re: some performance issues

Hello, Thanks a lot. I'll try a new build. I had the same test on VUPS (yes, basic DCL) with the same distribution which runs on a window server and I got 150 VUPS. Perhaps there is something specific about Itanium and OpenVMS there. Another question is: are there ways of specific

Re: [Simh] some performance issues

I have to wonder if a lightweight Linux disto, that has been locked down, running on a Core i7 might not give better SIMH performance. My *old* i7 ESXI box provides a faster “VAX” than my VAXstation 4000/60. What is the reason for running on Itanium? Zane > On Mar 6, 2019, at 1:57 AM,

Re: [Simh] some performance issues

Hi I'm having trouble understanding your question. Are you comparing CPU-time of a real VAX(which model?) to emulated CPU-time on an Itanium machine(which one?). Emulation will have an associated overhead. If you are compareing a fast VAX to an emulation on a slow Itanium... well, Itanium is
