title: How to determine buffer size
body: <p>Let me explain what information I need for this:</p>
  
  <p>I have several concurrent users hitting the same record at once. This means, there will be some queuing and locking going on, on the db end. How big is this buffer? Can queue and locking hold for 200+ concurrent users?</p>
  
  <p>How can I determine the size of this buffer in our setup? Is there a default setting?</p>
