||Istio, general use
||A load testing library and command line tool and web UI.
Allows to specify a set query-per-second load and record latency histograms and other useful stats.
||A simple HTTP request & response service.
||Finagle, general use
||A load generation tool that replays production or synthetic traffic against a given target. Among other things, it differs from other load generation tools in that it attempts to hold constant the transaction rate.
||Linkerd, general use
||A load testing tool that produces a predictable load and concurrency level for a long period of time. Provides periodic reports of qps and latency (during testing).
||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.
