Plain single-stream download-only TCP should fit without compression, probably even without Delayed ACKs. IME, the line starts to choke when you actually want to send requests and they compete with ACKs and your internet stutters and crawls in both direction. Though that was with a slower connection - it's harder to fill a bigger pipe. BTW, is the ACK compression counted for consumers benefit?
