.NET 9 Feature That Will Kill Node.js

I deployed a .NET application that starts in 12 milliseconds, uses 8MB of memory, and runs faster than the equivalent Node.js version

Last weekend (9th of August), I did something that would have been impossible two years ago.

I deployed a .NET application that starts in 12 milliseconds, uses 8MB of memory, and runs faster than the equivalent Node.js version

Yes you heard me right… let me repeat

I DEPLOYED A .NET APPLICATION THAT STARTS IN 12 MILLISECONDS, USES 8MB OF MEMORY, AND RUNS FASTER THAN THE EQUIVALENT NODE.JS VERSION!!

— as a standalone WebAssembly binary.

.NET 9 combined WebAssembly (WASM) with Ahead-of-Time (AOT) compilation in a way that fundamentally shifts the performance equation. .NET applications can run anywhere with startup times that make Node.js look glitchy! ewww

BEWARE — I’m not talking about replacing Node.js everywhere. But for specific scenarios — serverless functions, edge computing, browser applications — this combination creates performance characteristics that…
