About hey

hey is a tiny program that sends load to a web application, running a configurable number of requests at a chosen concurrency level and printing latency and throughput statistics. It supports HTTP/2, custom methods, headers and bodies, rate limiting per worker, timed runs, and CSV output for further analysis.
