I've read it on my way home. It is certainly true that we don't have SACK.

However, that we perform worse even than Linux without SACK, isn't
necessarily true. Their network loss simulator simulated constant
loss rate, but I'd expect, even on partially shared medium networks
like 802.11 and friends, a loss rate that depends on channel load.

Linux with its more aggressive retransmission (which the authors acknowledge)
would lead to higher effective loss rates and worse overall performance
(although not necessarily worse performance of the Linux connection).
