http-kit is clean and small, less is exponentially more

• HTTP server: event-driven, ring adapter, websocket extension, asynchronous extension
• HTTP Client: event-driven, asynchronous with promise, synchronous with @promise, keep-alive
• Timer facility

All the above + high concurrency + high performance + nice API + written from scrach = ~3K lines of code.

Clojure is awesome

Clojure + JAVA = Performance + Nice API

Less is exponentially more
