It seems Emacs thinks you work on a slow terminal and is adding delays.
To check this assumption add the following line to your .emacs or
evaluate it after starting.
    (setq baud-rate 56000)     ;; must for working faster (linux)
We had this problem on telnet (without SSH) on our system, the
above line solved it completely.

May it is time to drop the slow terminal support from Emacs altogether,
I don't think there are slow terminals (except may be in technological
museums) that have to have padding.

Ehud.
