wrk is a modern HTTP benchmarking tool that generates significant load from a single multi-core machine using a multithreaded design with epoll/kqueue event notification. It supports optional LuaJIT scripting for custom request generation, response processing, and reporting.

Use cases

• load test an HTTP API with thousands of concurrent connections
• measure requests per second and latency of a web server
• benchmark before and after a performance optimization
• generate custom HTTP requests via Lua scripts for load testing
• stress test a service endpoint for a fixed duration

When to choose

• you need high-throughput HTTP load generation on a single multi-core machine
• you want detailed latency statistics from a lightweight CLI tool
• you need scripted, customizable benchmark scenarios via LuaJIT

When to avoid

• you need distributed load generation across multiple machines
• you need a browser-realistic or protocol-rich testing tool (e.g., WebSockets, HTTP/2, JS execution)
• you want a GUI or record-and-replay workflow
