Actual behavior
The CPU usage while running tests in parallel should be comparable to the same run in python

Steps to replicate

  • Run gauge-tests for ruby
    mvn -q clean install -Denv=ci-ruby -Dtags="ruby"

Observations:

Platform: osx Sierra, on macbook pro late 2016 edition.

gauge tests execution's CPU usage observed (parallel runs, 8 streams):

  • gauge-java ~90%
  • gauge-ruby ~60%
  • gauge-js ~40%

multithreading was enabled for all the runs.

If this needs to be investigated further, we need to start benchmarking.
