title: How many TCP sockets can I open at once?
body: <p>I am going to develop a TCP  server application. I am on the "choose server" step.
  My TCP server is going to have 2000+ clients and one socket to each client.</p>
  
  <p>Is there limit for amount of created sockets depending on the operating system? Which operating system permits more open sockets at a given time?</p>
