This is equivalent to my test.
And then, I say "M-x customize-group RET RET" and have 4 TCP packets
per second (maybe cursor blinking). If I start the above command
again and say "M-x customize-group RET tramp RET", I have 60 packets
per second.

Then somebody must tell me how. ;-) I'm really not an expert in
packet sniffing. Those packages are encrypted, so Wireshark shows
me only garbage.

I think -X means that only the X port is forwarded. Besides, the
local machine has nothing else listening. There is no shared
directory, and no SSH server.
Tschö,
Torsten.
