## What it is
Muduo is a multithreaded C++11 network library based on the reactor pattern, providing event-driven TCP networking for Linux servers. It uses non-blocking I/O with epoll and one-loop-per-thread concurrency, and is widely used as a reference for learning network programming.

## Use cases
- build a high-performance TCP server in C++ on Linux
- learn reactor-pattern network programming
- write an event-driven multithreaded server
- handle many concurrent socket connections with epoll
- implement custom application protocols over TCP
- study a well-known C++ network library codebase

## When to choose
- you need a proven, readable C++ networking library for Linux servers
- you want one-loop-per-thread multithreaded I/O without manual epoll plumbing
- you are learning how production network libraries are designed

## When to avoid
- you need cross-platform support beyond Linux
- you want an HTTP framework or batteries-included web server rather than a raw networking library
- your project requires modern C++ beyond C++11 or a permissively licensed dependency (license is custom BSD-style)

## Facets
