The article argues that many modern APIs, once designed to be idempotent, pay an unnecessary cost for TCP’s ordering guarantees. By rethinking reliability, developers can leverage UDP’s simplicity for faster, more resilient services.

Mozilla engineers replaced Firefox's aging Netscape-era UDP stack with a Rust-based solution leveraging modern OS capabilities, yielding up to 4x throughput gains for HTTP/3 traffic. The journey reveals critical platform-specific optimizations—and pitfalls—for high-performance UDP I/O across Windows, Linux, macOS, and Android.
