In my case, gcc with the default makefile.   I don't use VC (or the OS it runs on) unless serious force is applied...

How was simh compiled? I used Visual C and the difference between running the compiler with optimization on or off made quite a difference for the generated code. And gcc might compile even faster codefiles.

Why is SIMH so slow though?

As far as I can understand, one MIPS is roughly one VUPS, correct?

So how come I get 14 VUPS on the same host running SIMH whilst my Hercules install peaks at 180?

Are the architectures that different (obviously they are) or what is it?
