Successfully set up Vino VNC server as described in the manual files on Jetson Nano desktop, it starts automatically with auto login turned on every time Nano boots, but it is incredibly slow to react - it takes about 2 seconds to react to either a click or a button press. Strangely enough in fact it is slow only to display it via VNC - everything executes almost immediately on the physical screen attached via HDMI.
Any ideas on making Vino snappier?
P.S.: FYI RasPi 3 with RealVNC Server flies on the same WiFi network with all the same conditions, so has to be an issue with Vino
