102: the spec (012) and a receiver written from it alone; the four holes
writing it found (REFUSED, the record's size, a peer's run places, the
memo's places beside) and the credit M6 showed fixed at 1,024 records;
M6 with ngtcp2 as a third, two rounds. Under reordering Pure carries the
most (45 Mbit/s; ngtcp2 29-47, quinn 1-2), under random loss the three
are the same, on a clean bottleneck Pure carries 3-5 % less (its framing,
some 112 B a packet to QUIC's 41), and where loss and reordering meet
ngtcp2 carries 1.3-3.6 times as much: undoing a loss it took for
reordering, it restores the window a real loss had cut too (its log: 22
of 34 undos past the window before the last cut; none without
reordering). Shares beside TCP stay within 25 %.
011 and the status table say so; 012 also says that a receiver answers
within 25 ms (a sender's PTO counts on it), that a shape and a record's
bytes are the app's, and why a packet of the past does no harm.
