[omniORB] Network performance

[Richard Hirst]

Have a look at nerperf.  See how fast that can bounce small packets
back and fore between the two machines in its RR tests (request-response).
That will give you an idea of what your hosts, NICs, and network are
capable of.  Some NICs throttle the maximum interrupt rate, for example,
which can really limit throughput in a request-response type of test.
