## What it is
gnet is a high-performance, lightweight, event-driven networking framework written in pure Go, built on epoll and kqueue with a reactor pattern. It operates at the transport layer (TCP, UDP, Unix Domain Socket) so developers can implement application-layer protocols like HTTP, RPC, WebSocket, or Redis on top of it.

## Use cases
- build a high-performance TCP server in Go
- implement a custom application-layer protocol like Redis or RPC
- write an event-driven network service with lower memory than Go net
- build a UDP-based networking application
- create a WebSocket or HTTP server from scratch on a fast event loop
- replace goroutine-per-connection networking for performance-sensitive services

## When to avoid
- you want a batteries-included HTTP framework with routing and middleware
- your workload is not performance-sensitive and Go's standard net package suffices
- you prefer goroutine-per-connection programming models
- you need application-layer protocols provided out of the box
