The problem here is that most Java ORBs multiplex concurrent requests to the
same server over one connection, but omniORB only implements a
thread-per-connection threading model on the server side. Therefore omniORB
can only process one request per connection concurrently.

The way omniORB implements its thread-per-connection model doesn't limit
concurrency if the client also opens a new connection for each concurrent
request. BTW, this is documented (in more detail) somewhere in the omniORB
documentation.


As far as I know (from reading this mailing list), this interoperability
issue will be addressed in omniORB 4; see
