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

20 packages every 5 seconds does not sound problematic. 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?
