So I think is working using NODELAY option... do you know a way to

I'll check around a bit...maybe on last set nodelay before send() or turn it off before send.

Found a patch in their system where they added a TCP_CORK flag but it's still marked open. http://www.freebsd.org/cgi/query-pr.cgi?pr=24959

Have Fun!
