Project mention: An Analysis of the Performance of WebSockets in Various Programming Languages | news.ycombinator.com | 2024-11-22
NodeJS beating C++ in these benchmarks makes me suspect the methodology / server setup since the NodeJS library[0] used is just a wrapper around the C++ library[1].

They explained why they did this here: https://github.com/zeromq/libzmq/issues/2376
Bottom line is that their licensing with a static linking exception was kind of weird and creating a lot of issues combining zeromq code even with other open source licenses (like Apache 2.0).
Interesting to see how they gathered permission to do this from the developer community. License changes like this are usually hard to realize unless you insist on copyright transfers. But in this case they managed to do it without that. So it was a collective decision. Hard to argue with that.

sobjectizer
An implementation of Actor, Publish-Subscribe, and CSP models in one rather small C++ framework. With performance, quality, and stability proved by years in the production.
Message Delivery Tracing aims to debug an application built on top of SObjectizer. In essence, it logs the primary stages of the message delivery process, allowing visibility into whether there is a suitable subscriber with the corresponding event handler.
