We Ralph Wiggumed WebStreams to make them 10x faster

The text discusses performance optimization efforts in server-side streaming, focusing on the use of WebStreams in Node.js, particularly in the context of frameworks like Next.js and React. It highlights the inefficiencies found in native WebStreams, primarily due to Promise and object allocation overhead, and introduces a library called fast-webstreams that reimplements the WHATWG Streams API using optimized Node.js streams. The library significantly improves throughput by minimizing Promise creation and leveraging Node.js's C++ internals, achieving substantial performance gains in scenarios common in server-side rendering, such as React Server Component streaming and multi-transform chains. The ultimate aim is to integrate these optimizations into Node.js itself, with contributions already underway, to enhance the performance of WebStreams without the need for external libraries.
