It was only ever designed to be a prototype and lessons were learned along the way resulting in a new version that is better suited for production use. inlets OSS has now been replaced by inlets PRO, a new version that does everything the original version did, but with secure de

How, in general, does Node.js handle 10,000 concurrent requests?
I understand that Node.js uses a single-thread and an event loop to process requests only processing one at a time (which is non-blocking).

I can not understand (yet) how it can be faster than a multi-threaded web server. I understand that multi-threaded w
