Understanding Netty 4 Thread Model: Master‑Worker Multithreading and EventLoop Design

Netty 4 employs a global multithreaded, locally single‑threaded (event‑loop) architecture where a boss thread pool accepts connections and delegates them to worker thread pools, each containing NioEventLoop instances with selectors, task queues, and pipelines, ensuring lock‑free, ordered processing while avoiding thread blocking.
