I have not used the PDP-15 simulator, but I have made timing measurements
on the HP 1000 simulator. On a 2.1 GHz Core 2 Duo machine, the simulator
executes about 47000 instructions per millisecond. A real HP 1000 E-Series
executed about 1580 instructions per millisecond, so SIMH is about 30 times
faster.
I would think that the PDP-15 simulator would be of the same order of
magnitude on similar hardware.
