WebStreams are a nice, ergonomic standard for streaming data. And they're fast too... right?

Turns out: not always. On servers, we found they're up to 10x slower than Node.js streams.

So we Ralph Wiggum'd WebStreams for the server, powered by Node internals ↓

An AI-assisted effort produced a significantly improved WebStream implementation optimized for server-side Node.js environments, achieving up to 14.6x performance gains while passing 1100 out of 1116 Web Platform Tests (WPT). The work was done autonomously and is being submitted upstream to Node.js for broader community benefit.

AI at its best. We Ralph Wiggum'd a better WebStream implementation optimized for server-side Node.js environments.

Up to 14.6x performance improvement, with 1100/1116 WPT tests passing. Autonomously.

We're working to upstream this work to Node.js for the benefit of all. https://t.co/tJsnhB9Evu https://t.co/URBSi6TZfs
