Hi Frode, Well some context this project, I inherited when I joined my current company, and one that offshore couldn't quite get working. While I know that historically they've had slower performance with NoVNC, and I think the issues were more on the high latency end, with customer on the other side of the planet. I know that IT is looking into local data centers to help this, but my current task is to figure out what knobs and dials I can tweak, to eek out a little more performance.
I'm not even sure how to test performance, other than putting it on a server, and have customers we are friendly with give it a try. Which is something we will do. Locally testing the performance seems to be fine. The latency between the vnc server and the Guacamole server(Guacamole in our custom app), should be minimal, as in Dev they are on the same box, and in Prod they would be in the same data center. I'll have to ask IT for some number on that, just to make sure. Right now I haven't set any encoding in the user-mapping file, so we just have the defaults. From what offshore told me this morning, offshore said these didn't make any difference. Not that I believe that. So are there things there that I can tweak? Also in my app I'm not using that file, but I do the equivalent, when I create the tunnel, setting the config. Right now I'm just setting the host, port and password. I've played with color-depth, which I can set to 16 or 24, I tried 8 but got a 515 error.
