wrk2

Wrk2 is an invaluable tool for developers and performance enthusiasts alike. It provides a robust framework for load testing and benchmarking web servers, allowing you to simulate real-world traffic scenarios with precision and ease. wrk2 is a constant throughput, correct latency recording variant of wrk. wrk2 (as is wrk) is a modern HTTP benchmarking tool capable of generating significant load when run on a single multi-core CPU. It combines a multithreaded design with scalable event notification systems such as epoll and kqueue. wrk2 is wrk modifed to produce a constant throughput load, and accurate latency details to the high 9s (i.e. can produce accurate 99.9999%'ile when run long enough). In addition to wrk’s arguments, wrk2 takes a throughput argument (in total requests per second) via either the --rate or -R parameters (default is 1000).
