My favourite part of that is "disabling TSO leads to a doubling in throughput". In precisely the sort of situation that TSO was intended to help throughput.
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."
