title: How many CPU cores does a Heroku Dyno have?
body: <p>I'm using Django with Celery 3.0.17 and now trying to figure out how many celery workers are run by default.</p>
  <p>From <a href="http://docs.celeryproject.org/en/latest/configuration.html#celeryd-concurrency" rel="nofollow noreferrer">this link</a> I understand that (not having modified this config) the number of workers must be currently equal to the number of CPU cores. And that's why I need the former. I wasn't able to find an official answer by googling or searching <a href="https://devcenter.heroku.com/articles/dynos" rel="nofollow noreferrer">Heroku's dev center</a>. I think it's 4 cores as I'm seeing 4 concurrent connections to my AMQP server, but I wanted to confirm that.</p>
