title: Max connection limit in php apache server
body: <p>I have 32 GB ubuntu server where my site is hosted. I have installed the XAMPP and running my site. So here my question is what is the limit of maximum concurrent connections apache will handle and how I can check that? At which extent I can increase it and how? 
  My server must have 5000 concurrent users at a time So for that I have to configure it. </p>
