This is not really an Asterisk development question... in reality it
isn't even an Asterisk question, since Asterisk doesn't do anything to
influence the kernel's scheduling of processes and threads.

You should send this question to the asterisk-users list, and you should
include the system details... you neglected to include kernel versions
and configurations, for example, and CPU scheduling behavior can be
radically different between kernel versions (and recent kernels have
multiple CPU scheduling options to pick from at compile time as well).
