It's not going to be possible to look at a screenshot of encrypted traffic and determine what's going on. That said, based on what can be seen, it looks like the following is true: 1) You are not measuring what you expect (multiple connections are present in reality) OR the HTTP tunnel is being used, which will indeed have bandwidth overhead. 2) Regardless of what you're measuring, 4 MB in 6 minutes is around 90 Kbps. I wouldn't expect this for an idle connection, but it is also definitely not high usage. Testing this myself, I see 17 Kbps of usage between browser and webapp for an idle RDP connection.

You should investigate what is actually being sent behind the scenes by capturing the unencrypted traffic. - Mike
