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
Basic Usage:
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.
Output:
Running 30s test @ http://127.0.0.1:8080/index.html
12 threads and 400 connections

LuaJIT script example:
script.lua:
-- example HTTP POST script which demonstrates setting the -- HTTP method, body, and adding a header wrk.method = "POST" wrk.body = '{"value":"ourdata","type":"example"}' wrk.headers["X-EXAMPLE-HEADER"] = "OurDataHeader"
Launch:
wrk -t10 -c50 -d30s -s script.lua https://api.example.com
Load testing with wrk when every reqeust has unique http hmac authorization header
