Wrk mini-howto

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
    Thread Stats   Avg      Stdev     Max   +/- Stdev
      Latency   635.91us    0.89ms  12.92ms   93.69%
      Req/Sec    56.20k     8.07k   62.00k    86.54%

  Requests/sec: 748868.53
  Transfer/sec:    606.33MB

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

Useful info

Load testing with wrk when every reqeust has unique http hmac authorization header
