Why isn’t bun utilising multiple cores?
Bun will eventually implement Worker/worker_threads and that will have an integration with the HTTP server for load balancing
I assume this has to do with how extremely experimental bun is at the moment anyway. So they are focusing on nailing the fundamentals before attempting anything that would make it „production ready“ such as multi core support.
As an aside, I’ve now seen a couple of HN submissions relating to Bun and there’s been a vibe that there’s conspiracy or foul play afoot in each. That’s a little … unusual. What does the developer seem like on Twitter, fairly normal or a bit eccentric?
That's inevitable when companies with big investments have to market a performance-oriented product to a public that doesn't fully understand the nuance of software performance running on modern hardware.
The average JS dev doesn't really know what's happening behind the scenes, so a precise message will not be nearly as effective as slapping together a long and a short bar in a barchart. And since this type of marketing is imprecise by nature, tweaking some details lets opposing parties corroborate conflicting claims.
I've been through this same phenomenon when working at Redis Labs. Everybody had the fastest cache and/or db. Both Redis Labs and each of its competitors. You just had to pick the right bar chart.
