[Message part 1 (text/plain, inline)]

I found the culprit was this line in my configuration:

(setq lisp-indent-function 'common-lisp-indent-function)

and common-lisp-indent-function is provided by

`.emacs.d/elpa/slime-20161109.640/contrib/slime-cl-indent.el'

I think it is a wrong configuration.

something in common-lisp-indent-function cause the huge slowing down.

thanks for your time and sorry for the false bug.
