This is indeed very interesting and somewhat unexpected. Do you have any clue why Y is as bad as R and so much worse than B? By my understanding I would have expected Y to be similar to B. At least tests on the Mean Response Waiting Time of sender limited flows show hardly any difference to B (as expected).
Also, is a potential longer time in TCPRecovLat such a bad thing considering your information on HTTP response performance?
