[Simh] SIMH vax.ini fine tuning

[Jason Stevens]

I'm also partial to the throttle command... I run a 11/780
(retromud.superglobalmegacorp.com) and 3% gives me the 'feel' of an older
machine ...  And my VPS provider hasn't complained about it either.... Which
is nice as you cannot do anything to spike the cpu to 100% .....
 
For what it's worth..

If you're using linux, then another thing you can use is "nice".
I always "nice" simh when it's running to keep cpu usage down overall.

nice is one of the handiest linux/unix tools around.
