My question is: What settings should I change in Windows to increase the download speed, to get similar results to Linux? (disabling auto tuning even reduced the download speed) I've tried fiddling around with the TCP auto tuning levels and even disabling TCP auto tuning, but this didn't cause a increase in download speeds. When downloading from the Linux machine the performance was similar to the Windows > Windows transfer.Īfter doing some tests it became clear that the TCP receive window doesn't grow large enough on the Windows machines, when the network latency is "high" (above 50ms). What I've noticed is that over the same network, with a Linux guest in Hyper-V, the download speed exceeded 400Mb/s! The RTT/ping between the servers is 72ms. The servers are located in Roubaix, France and New York, USA. Even though the available bandwidth is 1000Mb/s. I've been transferring some large (1gb+) files over HTTP (TCP) between two Windows servers, and noticed that the download speed never exceeds 10Mb/s.
