Its stream bytes are a function of their offset, so what ngtcp2 keeps to send again points into a pattern that never changes. run.py's drain_ngtcp2 measures both sides' CPU as drain_quic does. Five rounds each, both sides' CPU a message: 61 B Pure 0.280, ngtcp2 0.270, quinn 0.310 us; 1 KiB 2.62, 3.54, 3.94; 16 KiB 40.2, 54.4, 60.2.
