title: Elasticclient - after two minutes longer response time
body: <p>I hope somebody can help.</p>
  <p>I'm using the elasticclient where I set the connection uri to a pc on network e.g.: pcname.domain.com:port.</p>
  <p>When I use the client first time, the response will be around 5 sec. Second time same request takes ~400 milisec.</p>
  <p>Once I do not use the client for about 2 minutes it will again take 5 sec. Is there any settings what I can set to avoid this &quot;5 sec&quot; behaviour as much as possible?</p>
  <p>In case of I use localhost the same request of 5 sec will be 200 milisec, when i use second time, less than 100 milisec.</p>
  <p>Can somebody help pls? I checked the documentation as well as the source code, unfortunately I did not find the root cause.</p>
