Our Java Swing application uses sockets to communicate with a backend...

From the point of view of a CPU dispatcher, a dual threaded CPU chip,
with dual threading enabled, is two logical processors, as is a dual
core chip with both cores enabled. A single thread can be reported
as taking up to 1/P of the compute power, where P is the number of
logical processors in the system.
I think you should look very closely at the numbers of logical
processors enabled on each system. Probably, each of the systems
reporting 50% utilization has two logical processors, and each of the
systems reporting 100% has a single logical processor.

Thanks Patricia - it sure seems like a reasonable interpretation of
the usage percentages. We're checking it out
.
