Block propagation data from Bitcoin Cash’s stress test

TL;DR: During the stress test, blocks propagated through the non-China mainnet at around 300–1000 kB/s. This is pretty slow, and would cause problems with orphan rates if block sizes were frequently larger than 8 MB unless we improve our block propagation algorithms.
