title: Sidekiq multiple workers?
body: <p>I have a question regarding Sidekiq. I come from the Resque paradigm, and in the current application I launch one worker per queue, so in the terminal I would do:</p>
  
  <pre><code>rake resque:work QUEUE='first'
  rake resque:work QUEUE='second'
  rake resque:work QUEUE='third'
  </code></pre>
  
  <p>Then, If I want more workers, for example for the third queue, I just create more workers as:</p>
  
  <pre><code>rake resque:work QUEUE='third'
  </code></pre>
  
  <p>My question is...</p>
  
  <p>With Sidekiq, how would you start with multiple workers? I know you can do this:</p>
  
  <pre><code>sidekiq -q first, -q second, -q third
  </code></pre>
  
  <p>But that would just start one worker that fetches all those queues. So, how would I go to start three workers, and tell each worker to just focus on a particular queue? Also, how would I do that in Heroku?</p>
