title: Docker parallel operations limit
body: <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>
