The above command, starts iperf server on the windows machine, and it bydefault runs on the port by default. I find this a bit strange as I would expect TCP to ack when the data has been received at the final desination. How to install iperf? Security Notes - 1 year 5 months ago. It only takes a minute to sign up. So there is no need to clear the transferred file after the test.

Because as I iperc you can test between two computer How can I test that? How to install iperf? TCP Transmission Control Protocolis a reliable transport layer protocol used for network communications.
A detailed report of speed and bandwidth analysis is very much necessary for the deployment of network dependent application servers. So you can clearly see that, if you increase the Window size a little bit to tune TCP, it can bring significant difference to the throughput achieved. When using Linux there is no packet loss. Is that consistent with your findings? Home Questions Tags Users Unanswered.
