Mobile Web Performance: Optimizing TCP Congestion Control Algorithms

What this post added

This post introduces Cloudflare's work on optimizing TCP Congestion Control Algorithms, particularly for mobile networks. It highlights how traditional algorithms were ill-suited for the sporadic nature of mobile network congestion and explains how Cloudflare leverages its unique network position and real-time data to tune these algorithms, leading to significant performance improvements for mobile users. This marks an evolution in their performance optimization efforts, extending beyond caching and image optimization to the fundamental network protocols.
