TCP Throughput Limit #3 Once window size and available bandwidth aren’t the limit

0.7 * Max Segment Size (MTU)

Bandwidth <

Round Trip Time (latency) sqrt[loss]

M. Mathis, et.al.

• Double the MTU, double the throughput

• Halve the latency, double the throughput

(shortest path matters)

• Halve the loss rate, 40% higher throughput
