title: Track MongoDB performance?
body: <p>Is there a way to track 'query' performance in MongoDB? Specially testing indexes or subdocuments? </p>
  
  <p>In sql you can run queries, see execution time and other analytic metrics. </p>
  
  <p>I have a huge mongoDB collection and want to try different variations and indexes, not sure how to test it, would be nice to see how long did it take to find a record.. (I am new in MongoDB). Thanks</p>
