[e2e] TCP Performance with Traffic Policing

I understand, but the client iperf "window" setting (-w 64KB) is really the send buffer so only 64KB was attempted to be in-flight (not 4MB).

Are we in sync?

I just did not want the receiving side (server) to limit the performance.

The RWIN does "dip" as the server receives data, but the advertised maximum was 4M.

Hm. May I quote your original post?

50 msec RTT and bottleneck bandwidth = 10 Mbps, so BDP was 62,000 bytes.

Could this be a clue?
