For calculations sake, let us assume 0 think time and I can scale it up as I
increase the think times. 

So at 0 think times I should be able to get 20-25 concurrent SOAP requests
for a 2.0 Ghz CPU? How much memory would I need with the 2.0 Ghz CPU? Will I
see CPU max out at that point or RAM? With think times of approx 30 seconds
is it safe to assume I will be able to get 50 users from 1 mc?

The soap requests make the server hit several components (like DB, message
queues etc. ) which are non linear. And like all other systems soap
application server does not seem to be a bottleneck here.

that depends on how much think time you have between requests. a 2ghz CPU 
system should be able to simulate 20-25 concurrent soap requests due to XML 
parser performance. that's the primary limitation.

you can actually calculate the theoritical max concurrent load the server 
can handle soap webservices without running any tests, since xml performance

is linear.
