title: What is the number of processes in Laravel Horizon I should use?
body: <p>I have installed <a href="https://laravel.com/docs/5.7/horizon" rel="noreferrer">Laravel Horizon</a> to mange my queues, and inside the published config there are these settings:</p>
  
  <pre><code>'local' =&gt; [
      'supervisor-1' =&gt; [
          'connection' =&gt; 'redis',
          'queue' =&gt; ['default'],
          'balance' =&gt; 'simple',
          'processes' =&gt; 3,
          'tries' =&gt; 3,
      ],
  ],
  </code></pre>
  
  <p>In the <code>processes</code> setting:</p>
  
  <ul>
  <li>How can I determine the number of processes I should use in a real
  world app? </li>
  <li>Is there a limit?</li>
  </ul>
