Unless it's actually zero, any loss on the "outer" TCP stream will cause a retransmission, visible to the inner one as a sharp jump in latency of all data following the loss. Most TCP stacks don't handle that very well either.
- mlyle 2y agoSure, even when outer loss is pretty close to zero, it's conceptually not great. On the other hand, I get 400mbps over TCP-over-TCP connections, and can't connect in any other reasonable way. 400mbps > 0. Even tunneling in UDP is not great due to MTU effects.
