Why mobile performance is difficult

What this post added

This post highlights the significant challenges in mobile network performance due to high latency and packet variability, which negatively impact TCP's congestion avoidance mechanisms. It explains how packet loss on mobile networks is often due to environmental factors rather than congestion, causing TCP to incorrectly slow down connections. The post also touches on packet reordering issues during mobile handoffs. Cloudflare's contribution is presented as a solution by customizing TCP stack parameters on their web servers and actively monitoring/classifying connections to dynamically optimize performance for mobile users. This post also mentions the introduction of features like Rocket Loader, Mirage, Polish, SPDY, and Railgun as part of their ongoing efforts to improve network performance.
