I'd be very surprised if omniORB is slower than a SOAP implementation,
since SOAP just has a lot more work to do to generate and parse XML
messages, and the messages are much larger.

Can you post some more details about what your test is actually doing?
How much data are you sending in each call?  What kind of data is it?
Are you just doing simple calls, or something more exotic with callbacks
or something?

What kind of absolute times do you get for your calls?

Cheers,

Duncan.
