A couple of week ago, I've posted a pdf with performance evaluation for 
inter-node only using local TCP or Sharedmemory. I measured message 
delivery time, and message frequency, as a function of message size. 
Search for the "Shared memory image plugin" thread.

Obviously, these transports cannot compete with the nodelet architecture...
