[olug] TightVNC cpu load?

[Eric Penne]

I have a PC running a shaker table.  The shaker table is really loud and
many of the tests are for 2-24 hours.  Currently we have a VGA converter
that we run a long cable through the ceiling over to the closest offices
and a TV so that we can monitor the test software from a quieter place. 
This does not give us quick access to the Emergency Abort facilities of
the shaker table.  I would like to run a VNC server on this Windows
machine so that we can eliminate the long cable run and have access to the
Abort button.  I don't know what processor the machine is or if it is
running NT4 or Win2k.

The software has a continuously updating graph of the forces applied. 
What kind of load will this put on the processor to run a VNC viewer?  The
network is 100Mb/s.  We can minimize the graph and just monitor the
display boxes that show a half second updated box that is small.  The
Abort button needs to be displayed.  I don't plan on running compressed. 
If nothing is connected to the VNC server what kind of load will it put on
the processor?  Can the server just pull a portion of the screen (ie Abort
button)?  How much memory should be available on the server?

Thanks
Eric
