I would be very interesting in seeing some basic performance figures for the new transport.
E.g. two machines on commodity hardware, connected by gigabit ethernet (direct or through switch).
Test throughput for
1) One way invocations (both client-server and server-client)
2) Two way invocations
With a few different values for payload:
e.g. 256 byte, 1K, 10K, 100K
