Been working with VMS since 1983 when I joined Digital as a PDP-11 specialist.
I have an aging VAX 4000/900 running 5.5 with everything from ACMS to RDB that I want to try moving to the free emulator just to see how well it performs. Powered it up a month back and it is still kicking.
The company I work for has several Alpha's and we recently purchased a lot of used gear for backups. Now running on two GS1280-8's and many ES40's. We will likely move 5-6 ES40 single CPU systems to emulation within a year. We run the same COBOL application on HP-UX, but plan to migrate the HP-UX users to modern software running on Linux in a year or so.
Glad to be here! |

Welcome,
I do not know of any online site that has posted benchmarks comparing the various free emulator performance as compared to the real machines.
My guess is that on current x86 hardware, SimH/VAX would be lucky to get about 6 VUPs, but I could be very wrong about that.
The commercial emulators have more enhanced techniques in them to get faster performance.
