Docker parallel operations limit : <p>Is there a limit to the number of parallel Docker push/pulls you can do? </p>

<blockquote>
  <p>E.g. if you thread Docker pull / push commands such that they are
  pulling/pushing different images at the same time what would be the
  upper limit to the number of parallel push/pulls</p>
</blockquote>

<p>Or alternatively</p>

<blockquote>
  <p>On one terminal you do docker pull ubuntu on another you do docker
  pull httpd etc - what would be the limit Docker would support? </p>
