title: How to Perform loadtest on Node.js Application
body: <p>Please, I need an expert advice on how to efficiently test a finished Node.js Application.
  What I want to do is </p>
  
  <p><strong>1.</strong> I want to run the test to stimulate for example 100 users are all inserting data into a <strong>mongoDB</strong></p>
  
  <p><strong>2.</strong> 100 users retriving records from the db</p>
  
  <p><strong>3.</strong> 100 users are maybe deleting from the database, I want to check how the system will perform in situations like that.
  I read about loadtest in npm and it seems to me as a good candidate, but I don't know if I can use this to pass data(post/get) request into the database to actually, see how the system will respond to situation like 100 users all posting real data into the database.
  I suppose ,loadtest helps with checking the response time of eg 20sec with maybe 40 concurrent request, which is my basic undertanding of the module, I don't know if it has other functionlities like what I am expecting to do.
  Any advice or clue to go about this will be appreciated,because I wish to avoid re-engineering the wheel if possible
  Thank you</p>
