Well, Sai-Lai Lo wrote this in an older mailing to this list:

So I guess omniORB does NO multiplexing of requests over one connection.
It opens a new connection when necessary.
However, I always thought there is quite a big overhead for creating a
new (socket) connection and that is more efficient to multiplex the
request onto one connection instead of creating new connections. But it
seems I am wrong !!
