Cloudflare·34wCloudflare just got faster and more secure, powered by Rust
Cloudflare has replaced their core NGINX-based proxy system (FL1) with a new Rust-based modular proxy (FL2) built on their Oxy framework. The migration delivers a 25% performance boost with 10ms faster median response times, uses less than half the CPU and memory, and provides better security through Rust's memory safety guarantees. The new modular architecture allows faster product development, graceful restarts without dropping connections, and eliminates the incremental performance cost of adding new features that plagued the legacy system.
