In text-mode cursor reaction is immediate, no delay at all.

I get the same problem
(well timing is not exactly he same, but same order of magnitude)
with the 7.x version that came with my emacs.

I will do that. In the mean time, I may use Alan Schmitt's approach
(thanks Alan) to recreate my emacs environment and getting rid of old
stuff hanging around in my setup files.

I have to eliminate source(s) of conflict to solve an indentation
problem reported on this list (discussed with Bastien in thread 'org
mode alignment problem')

I will keep you posted about my findings / progress.
...
So here's the first posting: Found the culprit:
(require 'linum)
(global-linum-mode)
Turning global-linum-mode off solved he problem. Response time back to
normal (y)

Found this using the profiler as you suggested.

Threefold thanks!

With kind regards,

Guido.
