thanks for information.
To give some more details, is we execute:
ps auxwm
We can see that Asterisk is using quite many threads (33 threads in a
mainly new Asterisk installation)

Yes, I see that it uses threads. I wonder some other data like which is
the limit that core/CPU's are correctly used (or usefull used).
Thanks again Ryan,
