Michael Jumper commented on GUACAMOLE-270:
------------------------------------------

That is definitely unusual... Would you be able to provide a packet dump of the data to/from the webapp when you're seeing this?

I'd like to see what exactly is being sent to cause such high usage.

> I am using the latest docker image of guacamole/guacd (0.9.11-i) with RDP and Chrome and I have had some users complaining about extreme slowness when using it at home after hours. Looking into the issues, it seems that the upload bandwidth was being saturated. Which surprised me a little, because it's only 5 or 6 people using it. I tested it on my system and looked at the chrome task manager which shows bandwidth usage per-tab.
> What I found, is that when the screen is refreshing modestly, bandwidth usage is low. For example, I open the windows task manager and go the the performance tab which has a little scrolling graph that's always refreshing -- watching the chrome tab bandwidth usage with that little graph moving inside the guacamole window and the bandwidth is hovering around 50Kbps. But then, If I close that window, so that nothing on the screen is refreshing, the bandwidth jumps to 2Mbps and stays there until the screen refreshes again. 
> To reiterate -- when the screen is idle -- bandwidth usage is 2Mpbs. When the screen is active -- Bandwidth usage is < 100 Kbps
