# Building a Non-Blocking Multithreaded TCP Server in C++

The author built a simple non-blocking multithreaded TCP server in C++ to understand how servers work at a lower level, covering core concepts like TCP sockets, non-blocking I/O, and multithreading. Key challenges included thread management, race conditions, and mixing non-blocking I/O with threads, leading to appreciation for thread pools, event loops, and hybrid architectures. Future plans include replacing thread-per-connection with a thread pool, introducing epoll-based event-driven I/O, and benchmarking performance.
