Right, sendfile does not have any effect. I played around a bit with the TCP_MAXSEG socket option and with sender and receiver MTU sizes but nothing helps. The stack does not give me large packets if I switch on the NETIF_F_TSO flag. There must be some magic I'm missing.

Which kernel are you using? Recent kernels will obey TCP congestion windows, so they will not off the bat hand you a large packet, the TCP congestion window has to grow to larger than the mss to hand you a larger than normal segment.
thanks, Nivedita
