[ale] Mass Machine Virtualization w/ Remote GUI Access

[Jeff Hubbs]

The 8-CPU mobo might be overdoing it but maybe not 4...

Regarding Stephen A. DuChene's comment "We have found that even using a 
big server system with multiple GB of memory there is still a practical 
limit of around 4 - 8 people who can run VMware sessions off of a remote 
server," I wonder if that is caused by a RAM I/O bottleneck that the 
RAM-affinity of those boards can help get around.  That is to say, does 
it raise that limit or at least "soften the knee" if you're using these 
new Opteron boards?  Or, do I just have to buy one to find out? ;)
