Perhaps my recollection of history is suffering from bitrot, but I
thought the situation TSO was intended to help was when there wasn't
enough CPU horsepower on the sender to enable achieving the desired
transfer rate when going up and down the protocol stack at just 1460ish
bytes at a time. One of the reasons it was called (at least by some in
early days) "Poor Man's Jumbo Frames."
happy benchmarking,
