The most common issues are CPU on the guacd server and using HTTP instead of websockets. Here is how you can figure this out:
1. Run "top" on your guacd server, open a console to one of your Ubuntu hosts in a browser, then open a terminal window or something and drag it quickly in a circle while watching top. Note the CPU usage on your guacd server. If it is really high, either you are running on HTTP comms, your VM integration components are out of date, or the CPU just isn't powerful enough. Try setting "maximum performance" power settings and installing/upgrading your VM integration components. 2. Open a browser debugger (F12) and connect to an Ubuntu instance. Note the protocol being used for the connection. If you see a large number of HTTP requests that occur every second or so continuously, then you are stuck on HTTP and websockets are not working. This will cause massive overhead. If you find out that one of these is the problem, I can help point you in the right direction to fix it. If they are not the problem, I know a few other things to look at. -- View this message in context: http://apache-guacamole-incubating-users.2363388.n4.nabble.com/Guacamole-0-9-12-WAN-Performance-Ubuntu-14-XDRP-tp1040p1043.html Sent from the Apache Guacamole (incubating) - Users mailing list archive at Nabble.com.
