[Simh] SIMH tweaks/tips. [Deathrow DAHMER:: Node]

I found that turning on all of the optimizations in Microsoft C made a
significant difference.  I have modified my version so that it automatically
shuts down VMS & the emulator if someone shuts down windows.

My current version is about 470KB in size & gives me ~ 7 VUPS ON A 1.5 Ghz P4.

If you want to try my compiled version, I can zip it up & email it to you.  The
autoshutdown stuff needs a couple of tweaks to the registry to work - I will
include that info- if you are interested....

	Hello all..

 	I've upgraded the Deathrow cluster node DAHMER (SIMH node) to V3.8-1.
The old version was working just fine (no problems to report) in the cluster,
but I decided to "tweak" the node a bit.   Things like SSH connections take
a long time to get established.  Not a huge problem,  but upgrading and tweaking
seemed like a fun thing to do this Sunday afternoon. 

	On thing I did was used the Intel C compiler to build the VAX/SIMH code.
I haven't done any testing to see if it's really any faster. 

	My question is,  anyone have any tips on speeding up SIMH?  It's not
that I'm disappointed or anything (the speed is pretty good),  but more is
always better.   Thanks again!
