About:
Wrk is a modern HTTP benchmarking tool designed to generate significant load with minimal overhead. It combines multiple worker threads and an event-driven architecture to test the performance and scalability of web servers and APIs. The tool provides detailed latency statistics and throughput metrics, making it ideal for performance analysis.
Key Features:
  • High-performance multi-threaded engine
  • Scripting support via LuaJIT for complex scenarios
  • Low overhead for accurate measurements
  • Detailed latency and throughput reporting
Use Cases:
  • Load testing web servers and application APIs
  • Measuring performance impact of code changes
  • Capacity planning and scalability analysis
Alternatives:
  • ab – ApacheBench is simpler but less performant and feature-rich
  • hey – Hey is Go-based and easier to install but lacks Lua scripting
  • k6 – k6 offers more advanced testing features but is heavier to run
