title: Slow pagination over tons of records in mongodb
body: <p>I have over 300k records in one collection in Mongo.</p>
  
  <p>When I run this very simple query:</p>
  
  <pre><code>db.myCollection.find().limit(5);
  </code></pre>
  
  <p>It takes only few miliseconds.</p>
  
  <p>But when I use skip in the query:</p>
  
  <pre><code>db.myCollection.find().skip(200000).limit(5)
  </code></pre>
  
  <p>It won't return anything... it runs for minutes and returns nothing.</p>
  
  <p>How to make it better?</p>
