Wtf does this do

Typhoon is a web server built in Ruby that's designed to handle many simultaneous connections efficiently. Instead of creating a new process or thread for each visitor, it uses an "evented" approach, think of it like a receptionist who takes notes on what each customer needs and checks back with them as soon as their request is ready, rather than assigning a dedicated staff member to each person. This lets the server handle far more concurrent users with less computational overhead. The main benefit for developers and site operators is performance. By processing requests more efficiently, Typhoon can serve more traffic from the same hardware compared to traditional Ruby web servers like Puma or WEBrick. If you're running a Ruby application and dealing with lots of simultaneous connections, whether that's a high-traffic API, a real-time application, or just trying to squeeze more value from your servers, a faster, lighter-weight server can make a real difference in response times and server costs. At a high level, Typhoon accepts web requests and routes them through an event loop rather than blocking on each connection. When a request comes in, the server registers it and moves on, only processing it when data is ready. This non-blocking approach is standard practice in languages like Node.js and Go, but less common in the Ruby ecosystem, which is why Typhoon stands out. The README doesn't go into detail about setup, features, or use cases, so if you're interested in trying it, you'd want to check the project's documentation or code on GitHub directly. It's a niche project aimed at Ruby developers who want the performance benefits of an event-driven architecture without switching to a different language.
