Linux tcp code seems to indicate that the maximum value of congestion windows snd_cwnd should not exceed the value of snd_cwnd_clamp which most of the time is 65535. Is that correct? If so does this mean that over a path with RTT of 1s and available bandwidth of 1gbps , the maximum achievable rate is 786mbps for an MTU of 1500 bytes provided the connection is not limited by the sending and receiving buffer size.
