Executive Summary & Key Takeaways
Unlock maximum network throughput and reduce packet latency by enabling Google TCP BBR congestion control and tuning sysctl socket buffers.
Enabling Google TCP BBR
Traditional TCP Cubic relies on packet loss to detect congestion, throttling speeds prematurely on lossy mobile or long-distance international routes. Google BBR measures actual bandwidth and round-trip times, delivering 2x to 10x throughput increases across high-latency connections.
