Also, what are you doing when you see this utilization and base64-encoded PNG images? Is this when the connection is idle? Or are you watching a YouTube video on the remote system? It matters. And it seems like you've jumped back and forth between talking about idle connections and now talking about...?? There's very little context to your assertion, here. Sean makes a really good point, and, really, it brings us back to one of Mike's questions, Manoj: what problem are you trying to solve? Are you seeing congestion on the network when you use Guacamole? Is the Guacamole connection unreliable or slow or choppy? Are you seeing high resource utilization for the Guacamole components or the web browser? -Nick >
