Honestly, I cannot reproduce the effect. How do you start Emacs through the tunnel? I have done it via ssh -X otherhost /usr/local/src/emacs/src/emacs -Q > The reason seems to be that Tramp causes X network traffic > (approx. 20 TCP packages) every 5 seconds.

But as I said, I cannot see a difference in network activity with loaded / not loaded Tramp. Could you, please, analyze these additional packages in more detail? Which port are they speaking to, which application is behind? Is it really X? > Tsch=C3=B6, > Torsten. Best regards, Michael.
