In addition to the baseline measurements, it would be interesting to see a
comparison on how the ORBs scale as the number of concurrent clients
increases. In omniORB, we have been careful to minimise thread
contentions and thread switching within the runtime. This pays off as a low
per-call overhead. I believe this will also have a significant positive
impact as the load on the server increases.
