title: MongoDB concurrent queries limit?
body: <p>Is there any limit of concurrent queries that mongodb can run in a second?</p>
  
  <p>I am trying to implement an API that runs 300 queries in each request in mongodb.</p>
  
  <p>So if there are 100 client requests in a second so the number of queries becomes 100 x 300 which is resulting in high latency. </p>
  
  <p>Any clue?</p>
