lucascs@protonmail.com Lucas C.S. Vegeta drives HTTP load at a constant request rate, rather than with a fixed pool of workers. The difference matters: a worker-pool tool slows down when the target slows down, hiding exactly the degradation you are measuring, while a constant-rate attacker keeps the pressure and records the latency it causes. It reports latency percentiles and can plot results, and works as both a CLI and a Go library. https://github.com/tsenart/vegeta/issues tsenart/vegeta
