16s in one case a "10 seconds freeze": it sounds to me like you *do*
reproduce the problem.
The only difference is that with actual keyboard input pending the
redisplay is partly prevented which is what you perceive as "freeze",
but the real problem is the time it takes.

Yes. Of course, that depends not only on Emacs's code and the
optimization level, but also on your CPU and your keyboard
repetition setting.
