MINA doesn't manage it. IoSession.write() usually causes one system call. > 3)Adjust TCP windows for the Bandwidth Delay Product.

Yes, it differs between diferent operating systems, so you'll have to refer to the manual if you want to tune at such level. I think it's just enough to adjust buffer sizes though.
