Network performance update: Security Week 2024

What this post added

This post provides an update on Cloudflare's network performance benchmarking, detailing improvements in 95th percentile TCP connection times and highlighting the impact of HTTP/3 adoption. It introduces a refined methodology for network selection, ensuring a consistent set of top 1000 networks for measurement. The post quantifies Cloudflare's performance advantage over competitors like Amazon CloudFront, Google, Akamai, and Fastly, showing it as the fastest provider in 44% of measured networks for TCP connection time and 73% for mean TCP connection time. It explains how HTTP/3, built on QUIC, accelerates connection setup by enabling parallel TLS encryption and connection establishment, leading to significant latency reductions.
