title: How do I find maximum number of concurrent connections that a server can handle?
body: <p>I want a java program, which can find the maximum number of concurrent connections that a server can handle ?</p>
  
  <p>You can assume that the server is http server.</p>
  
  <p>To be more clear:</p>
  
  <p>There are lots of opensource NIO frameworks. I want to pick one for my project. And want to test which implemenation supports maximum number of concurrent connections. Some of these frameworks claim that they support these many. But I want to get it verified myself before chosing one.</p>
  
  <p>My intentions is to support as many concurrent connections without dropping/rejecting clients?</p>
