Mutalisk

Mutalisk is a simple yet powerful HTTP API benchmarking tool.

Mutalisk emulates wrk, combines the power of multi-threading and IO-multiplexing.

Installation

Add this line to your application's Gemfile:

gem 'mutalisk'

And then execute:

$ bundle

Or install it yourself as:

$ gem install mutalisk

Usage

Do it in wrk style:

$ mutalisk -d 5 -t 2 -c 50 --latency http://v2.same.com/channel/1070566/senses

Sample output:

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
