We need 2 things to investigate this:

 . a clear recipe to reproduce the problem
 . some understanding what customizations in your .emacs cause the
   problem

For the latter, please selectively disable portions of your .emacs
until you arrive at the minimal self-contained portion that causes the
slowdown.  Then post that portion (together with a precise recipe to
reproduce the problem) here.

Thanks in advance.
