What does a number of cores of "~2, bursted" mean? : <p>According to <a href="https://docs.travis-ci.com/user/ci-environment/#Virtualization-environments" rel="noreferrer">the docs</a> the sudo-enabled environment offers "~2" cores, "bursted". I don't understand what that is supposed to mean.</p>

<p>I think there's a hint in <a href="https://blog.travis-ci.com/2014-12-17-faster-builds-with-container-based-infrastructure/" rel="noreferrer">this blog post</a>:</p>

<blockquote>
  <p>The build containers in our legacy build infrastructure have had 1.5 cores (with burst capacity)</p>
</blockquote>

<p>Sadly I don't know what "burst capacity" is.</p>

<p>I have asked this question before <a href="https://github.com/travis-ci/travis-ci/issues/6191" rel="noreferrer">on the Travis CI issue tracker</a> but since I got no answer I hope that I may find one here.</p>
