wrk - a HTTP benchmarking tool
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.
An optional LuaJIT script can perform HTTP request generation, response processing, and custom reporting. Details are available in SCRIPTING and several examples are located in scripts/.
wrk -t12 -c400 -d30s http://127.0.0.1:8080/index.html
This runs a benchmark for 30 seconds, using 12 threads, and keeping 400 HTTP connections open.
