If your system is already cpu bound then your intuition may be wrong. more threads means more context switching overhead reducing overall throughput, each request takes longer because they get a smaller share of the cpu, and a larger memory overhead (memory usage is proportional to the number of threads)
It's possible to add more Zeo Clients which will produce more available threads. I don't want to buy more machines if the machines we have aren't being using to capacity. If there is a way to see that the Zeo Clients are getting more requests than they can handle and thus queueing up requests it is probably time to add more machines. -Brian
