TCP Throughput Calculator

Estimate maximum TCP throughput based on window size and round-trip time.

TCP Window (KB)

RTT (ms)

Link Speed (Mbps)

Max TCP Throughput10.49 Mbps

Efficiency1.0%

BDP (bandwidth-delay product)6104 KB

Ideal Window6104 KB

To fully utilize the link, set TCP window size to 6104 KB (the bandwidth-delay product).

Max throughput = Window Size / RTT. Capped by link bandwidth.
