Abdon, The throughput measurement of VNC Viewer is fairly rough, and based on the time taken to receive updates from the server. Looking at your log, though, it does appear that some aspect of the computer's network setup is causing extremely high network delays. Have you checked the network error count of your network card? If it's very high then TCP will retransmit data and throttle-back the connection to a lower throughput.
