VNC slow connection on Ubuntu 16.04 in Intel NUC

Question

I have Intel NUC and have installed Ubuntu 16.04 on it. Everything seems to work fine when accessing the NUC to hdmi monitor. I have installed VNC on it and enabled its remote connection. I can connect to it from anywhere I want but the connection looks very slow.

I have checked the network on both the ends and the network is pretty good but don't know why the VNC connections are very slow. Is there any settings which I can enable/disable to improve the connection speed.

Thanks

Solution

Ubuntu default desktop is a bit slow, so I have installed xfce4 desktop by using command

sudo apt-get install xfce4

after this the connection is very stable and fast.

Thanks
