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.

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…

A 12x performance boost to Node.js — I recently hooked up my Raspberry Pi 4 to my TV and because I hadn’t benchmarked something in a while I decided to see if I could serve 100k HTTP req/sec from this little thing, over an actual Ethernet cable. I began by installing Ubuntu Server 20.10 …

A technical explanation for those interested in the gory details — Imagine being a paperboy, tasked with delivering letters to a set of houses by car. Would you drive around all houses, delivering one letter at every stop, going round all houses many times until you have no more letters to deliver? …

Newly released Deno 1.0 does not make any sense to me — 10 years ago we saw both Node.js and Golang release for the first time. Node.js was adopted at a rapid rate by scripters fed up with the old PHP/Apache set-up. Golang had a slower start to its adoption, opting for a co-routine design from the very start, probably discouraging unfamiliar…

Practical benchmark of TLS 1.3 WebSockets on limited hardware — If you’ve ever checked your stocks during the virus outbreak, you might have noticed that valuations are updated without you having to reload the page. This happens with Yahoo Finance, TradingView and many others. These updates are due to WebSockets, persistent connections that receive updates whenever they are sent. The…
