+RSocket is flat: the server produced exactly what request(n) asked for.
+gRPC grows 9.5x between 0.5 s and 2 s; WebSocket grows 13.2x.
+Growth that tracks the wait, rather than settling at a buffer size,
+means nothing bounded the producer. (Growth is faster than linear
+because the loop is still being JIT-compiled during the first run.)
