Dropbox have a good real-world comparison [1] between BBRv1 and BBRv2. They found the retransmission rate to be 4x lower for v2. It's on their edge network, so

Dropbox have a good real-world comparison [1] between BBRv1 and BBRv2. They found the retransmission rate to be 4x lower for v2. It's on their edge network, so would be interesting to see how v2 performs on connections with a high bandwidth delay product.
