Chris Wheeler created GUACAMOLE-270:
---------------------------------------
Summary: Guacamole consumes an incredible amount of bandwidth when
idle
Key: GUACAMOLE-270
URL: https://issues.apache.org/jira/browse/GUACAMOLE-270
Project: Guacamole
Issue Type: Bug
Components: guacamole
Affects Versions: 0.9.11-incubating
Environment: RDP Docker Chrome
Reporter: Chris Wheeler
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
