[omniORB] omniORB performance

BTW, Visiborker supports this too. At default Visibroker allocates one
thread to a group of session, default 5 I believe. The idea is that usually
only a few calls are made. Creating extra threads causes increased memory
use, but if you insist:

BOA_init( ..., ..., "TSession") ;

instead of TSingle or the defaul TPool.

Also check out this:

They come to the same conclusion with repect to throughput figers but also
notice that with inter-ORB connection omniORB is limited because:

"The omniORB server is unable to process requests sent in parallel over a
single connection, thus it serializes requests from multi-threaded clienst
that send requests over a single connection."

But if I remember a post in this list three weeks or so agao,  I believe
that is better solved now.
