Anyway, under the > tunnel ([2]), when SACK worked, it saved you a lot of retransmits. Hmm... Actually, after re-checking, there weren't much more of those retransmits at all. In [1] there was one more packet lost, so it took a bit longer. In [2] (with SACK) the retransmit started earlier and the rcv window was unchanged. So, it rather looks like differences in timing of TCP recovery techniques.
