## What it is
gev is a lightweight, high-performance non-blocking TCP network library and WebSocket server for Go, built on the Reactor pattern with epoll/kqueue event loops. It supports custom protocols, multi-core work goroutines, ring-buffer read/write, SO_REUSEPORT, and scheduled tasks for building fast servers.

## Use cases
- build a high-performance TCP server in Go
- serve WebSocket connections with low overhead
- implement a custom binary protocol server
- replace net stdlib for event-driven networking
- handle many concurrent connections with few goroutines
- build an echo or proxy server with epoll/kqueue

## When to choose
- you need event-driven, non-blocking TCP or WebSocket serving in Go
- you want custom protocol support on a fast reactor event loop
- you need SO_REUSEPORT, idle connection cleanup, or scheduled tasks built in

## When to avoid
- you need full HTTP/1.1 or HTTP/2 application server features
- you prefer the standard net package's blocking, goroutine-per-connection model
- you need TLS-heavy or platform support beyond epoll/kqueue systems
