The Distributed Systems Research Group of the Charles University, Prague, has produced a report on comparing omniORB2 and two commercial ORBs- Orbix and Visibroker. The  report contains performance comparsions of the three ORBs under various test conditions. Under most test conditions, omniORB2 is significantly faster than the other ORBs. A copy of the report is also available here.

We have carried out some simple performance measurements of omniORB2 on a number of different platforms, and also compared to a selection of commercial ORBs. The comparisons are for round-trip times to echo a null-string, in microseconds, and are the average of 5000 invocations.
