title: signalR overhead
body: <p>I have a client which updates its position on the server by periodically (each 4 seconds) sending it's new location. I also have a client which tracks the previous mobile, by periodically pollen the server (each 5 seconds) and get the latest location.</p>
  
  <p>Should this communication be carried over SignalR (for sending the latest location) or by using a timer? I say this as SignalR has some overhead which generates larger request sizes which can be very costly.</p>
  
  <p>Thank you,
  RYan</p>
