[omniORB] How to change buffer size?

[mail at dwol.de]

Hello,

in newsgroups I read that it´s possible to increase the transfer rate by
changing the default TCP/UDP buffer size.
How can I do it in OmniORB 4.0.3?
In omniORB_2.7.1 it was probably possible to change a value
tcpSocketMTfactory.cc, but this file was deleted by an update.

Thank you.

Dennis
