Hi nick,

Yes , I am seeing encoded images at idle connection and frequently packet
send recive ACK and SYN through server to client and vice versa .

I am  seeing high resource utilization for the Guacamole components on the
web browser.

I am also cross check bandwidth utilization RDP with using MSTSC ActiveX
control its too less (1.3 kbps) in running mode . in idle mode they can not
utilized network .
