Depending on your level of visibility into the network, you might look at various components and see if you're noticing packet loss - you may not see this on the ends of the network (the client, the RDP server, or even the guacd server), so just because you look at network statistics there and don't see packet loss doesn't mean it isn't occurring. My other suggestion would be to attempt to locate guacd closer to the RDP server- on the same network segment, etc. You may also need to locate Guacamole Client (Tomcat) closer, as well, but that's something you'll have to experiment with to see what works better. -Nick
