simh simulation speed

[Tom Jennings]

I haven't had a chance to get back and debug, but is it true that simh
does NOT simulate the target machine's execution speed? I wrote a simple
'sum all words in track N' program for the LGP and it completed as soon
as I hit return! It should have taken many seconds... I did RTFM, so no
reference to it, but I haven't had time to go look at the source. Got
lazy and decided to post instead of research (typical, huh :-)
