title: How to performance test MongoDB Storage Engine for website Session data?
body: <p>I'm looking to utilize MongoDB for session data storage, so we don't need sticky sessions in our load balanced environment.</p>
  
  <p>As of 3.0, we can use different storage engines within MongoDB.
  While MMapV1 and WiredTiger come out of the box, it's also possible to run other storage engines (RocksDB?).</p>
  
  <p>What I would like to do is test out my website using MongoDB with the different storage engines backed behind it.
  I currently have a JMeter script that will hit multiple pages on the site for many different users.</p>
  
  <p>Between tests I can switch out the Mongo connection, to different Mongod instances on different storage engines.
  All I can really take out of this is the average latency for the page loads in JMeter.</p>
  
  <p>Is there better results I can find, possibly using different tools or techniques?
  Or, for session data, which is heavily read/write, is there one storage engine that would be preferred over another?</p>
  
  <p>I'm not sure if this question is too open-ended or not, but I thought I'd ask here to maybe get more direction about how to test this out.</p>
