The Nagle alogrithm is assumend to be enabled but it should not add any
delay because my data is greater then one mss. But may be it does, do
you have any negative/possitive experience of the Nagle algorithm when
doing comparisons with TCP and SCTP ?

Torbjörn,

Are you turning Nagle off (on by default) on your TCP tests?
