## What it is
A collection of Go TCP server implementations benchmarked at supporting 1 million concurrent connections, comparing goroutine-per-connection, epoll, prefork, and workerpool (Reactor) approaches. It includes throughput and latency test results plus Linux kernel tuning guidance.

## Use cases
- benchmark tcp servers handling 1 million connections in go
- compare epoll vs goroutine-per-connection performance
- learn how to write high-concurrency tcp servers in go
- tune linux for massive numbers of tcp connections
- understand reactor pattern and prefork server designs

## When to choose
- you want to learn or benchmark extreme-concurrency TCP server patterns in Go
- you need reference epoll-based server/client implementations
- you want real throughput and latency numbers for different concurrency models

## When to avoid
- you need a production-ready TCP server framework
- you need a maintained library with a license and active releases
- you target platforms other than Linux, since epoll is Linux-specific

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: benchmarking, http-server, networking, concurrency
- domain: networking, performance, developer-tools
- platform: go
- tags: epoll, tcp-server, c10k, high-concurrency, goroutines, reactor-pattern, linux
