[omniORB] performance comparison

[Anil K. Gopinath]

It is important to realise that just the throughput of
the basic data types does not mean that the "performance
of ORB A is better than ORB B". I think we also need to  
consider tests which bring out other aspects of 
"ORB performance" (like scalability tests, marshalling 
tests, de-multiplexing tests, latency tests etc.)

Another aspect about performance of CORBA objects is that it 
is very sensitive to the operating environment (OS, Network,
ORB middleware, compiler optimization, thread package etc.). 
Hence, it would be better to run the performance tests  
individually in ones operating environment rather
than depend on results from other operating environments. 


We are in the process of creating an integrated approach
to automate the performance measurement and analysis of ORB 
endsystems. We are also developing a benchmark suite which 
can be used by ORB vendors and users to compare the 
"performance" of their ORB with other ORBs.


We have compared the performance of CORBA objects in different
operating environments and I should say that omniORB does show
a significant "high performance". I would like to call it 
"the high performance ORB " :)

ACE/TAO follows the POA, so it may not be fair to compare OmniORB
with TAO.
