## What it is
go-wrk is an HTTP benchmarking and load-testing CLI tool written in Go, inspired by the wrk tool. It uses goroutines for concurrent async IO to generate significant load from a single multi-core machine and reports throughput and latency percentiles.

## Use cases
- load test an http endpoint
- benchmark requests per second of my api
- measure latency percentiles for a web server
- stress test localhost service with concurrent connections
- compare http server performance
- generate high load from a single machine

## When to choose
- you want a wrk-like HTTP benchmarking tool that is easy to install via go install
- you need configurable concurrency, duration, headers, methods, and request bodies
- you want latency percentile and throughput reporting without extra setup

## When to avoid
- you need distributed load generation across multiple machines
- you need scripted scenarios beyond simple HTTP requests or playback files
- you require a GUI or rich metrics dashboards
