If the server has 100Gb link, and the client a 1Mb link, TSO is hardly making a difference in trains. Sending 10 consecutive 1500 bytes packets or one 15000 bytes packets will have the same effect, unless the sender is serving thousands of clients and a FairQueue interleaves packets. One solution is at the producer level (TCP stack of the sender in this case) to properly pace the transmits in MSS units given the RTT and cwnd, supposedly done with TCP Hybla. _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
