Gosh darn it he broke my shit on purpose! — In the year 2018 when uWS was at experimental version 0.14.x, I posted an empty package to NPM with the README file saying in big black ink: “I no longer publish to NPM. Find me elsewhere.”. This was when the project moved to GitHub where it remains to this date. …

Web benchmarks aren’t about the hugest number — When we see web benchmarks presenting a gazillion requests per second, the most common critique goes something like “this doesn’t matter for any real world application and people who care are fools”. …

It’s easy to win with twice the disposable computing power as your adversary — Presented below, by the Deno crew, is the claim that Deno outruns up and coming Bun when it comes to HTTP. There’s a small win for Deno presented, with Bun right after: Now, even if we take the numbers given and swallow them whole, there’s an awfully important detail omitted…

Finally a JS runtime made to perform — running circles around both Deno and Node.js — Ever since I published uWS for Node.js 7 years ago, my main point and what I have been trying to explain has been: look, JavaScript runtimes/servers can perform much better if made optimized from the start Of course in this day and age, any criticism in whatever form, immediately gets…

Early HTTP/3 for Node.js with performance metrics — Nightly builds of uWebSockets.js now ship with experimental HTTP/3 support*. Let’s take it for a spin! npm install uNetworking/uWebSockets.js#binaries Just like you’re used to, server endpoints are defined via an easy-to-use URL router with pattern matching and wildcards: const uWS = require('uWebSockets.js'); uWS.H3App({ .key_file_name: './key.pem', .cert_file_name: './cert.pem' }).get('/*', (res…

Early performance testing of QUIC support in uWebSockets on M1 MacBook Air — uWebSockets is an HTTP & WebSocket server library, getting QUIC and HTTP/3 support soon. Right now there is a minimal, highly incomplete and experimental example, recently benchmarked. Compile with “WITH_BORINGSSL=1 WITH_QUIC=1 make” This example is a simple but complete HTTP/3 server with header compression and a simple response. The idea…

I brush my teeth like Jhonny. Jhonny has no cavities. Therefore I have no cavities. — False marketing A common logical fallacy is the Association fallacy — Rust is hyped and proven to be fast and reliable — Deno is written to some small degree in Rust; therefore it has to be fast, as Rust is! Nope — it still can’t even beat Node.js. This marketing trick was…

Initial performance expectations for upcoming QUIC support — I am currently implementing QUIC support in µWS and as usual, thorough benchmarking and market research is a key first step. As a comparison I compiled the Node.js v15.0.0 source code with the — experimental-quic flag set, enabling core support for QUIC. …

Newly released Deno 1.9 promises “Rust-like” performance, still outrun by Node.js — There is no incentive swapping to Deno, especially not from Node.js. Node.js has history and is not exactly a performance beast on its own, but it does have strong support for native add-ons. These can seamlessly augment and boost Node.js to heights way above what is possible with Deno. Above…
