title: WebRTC: slow data transfer
body: <p>I'm sending data between two peers in pretty much the same way as in this demo, except between peers in different tabs, not on the same page: <a href="https://webrtc.github.io/samples/src/content/datachannel/datatransfer/" rel="nofollow noreferrer">https://webrtc.github.io/samples/src/content/datachannel/datatransfer/</a></p>
  
  <p>With two Chrome windows on the same laptop, I'm getting about a 10MB/s transfer speed - that's not very fast!</p>
  
  <p>Any ideas why it is so slow and what I can do to improve it?</p>
