Have you tried loading just Viper after "emacs -Q"?

Consider also using Vim-mode instead: http://www.emacswiki.org/emacs/VimMode

To debug the issue you are experiencing, you would need to profile all 
functions involved whenever you press a key, but - AFAIK - currently 
Emacs lacks a call-tree generator.
