I am using PuTTY (Win 10) to SSH-tunnel a remote VNC desktop (CentOS 7).

After login, if simply typing in a PuTTY's terminal, I can get instant display echo; however, if typing in a VNC terminal, there is significant displaying lag.

I am wondering if anyone has experienced the same situation and figured out the reason?

With simple terminal you send text and receive text (this is somewhat simplified but close enough).

With VNC you receive graphics, in general that's more data (or lots more, depending on configuration).

It transmits the keyboard and mouse events from one computer to another, relaying the graphical-screen updates back in the other direction, over a network.
