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.

Basic Usage

  wrk -k -t8 -c400 -r10m http://localhost:8080/index.html

  This runs wrk with 8 threads, keeping 400 connections open, and making a

  total of 10 million HTTP GET requests to http://localhost:8080/index.html

  Output:

  Making 10000000 requests to http://localhost:8080/index.html

    8 threads and 400 connections

  Completed 2516980 requests

  Completed 5033960 requests

  Completed 7550940 requests

Benchmarking Tips

  The machine running wrk must have a sufficient number of ephemeral ports

  available and closed sockets should be recycled quickly, especially when

  HTTP/1.1 keep-alive is disabled.

  To handle the initial connection burst the server's listen(2) backlog

  should be greater than the number of concurrent connections being tested.

Acknowledgements

  wrk contains code from a number of open source projects including the

  'ae' event loop from redis, the nginx/joyent/node.js 'http-parser' and

  the Tiny Mersenne Twister PRNG. Please consult the NOTICE file for
