Like Jason, I am also interested to know why the tickless kernel causes
the timers to generate so much more load.  I can't find anything
documented anywhere, really, about the issue — and this thread is the
only thing Google turns up on the topic.

I am looking to move my SIP system to FreeSwitch some time soon, if
I can, but I would love to know why nohz is so hostile to FreeSwitch
before I do, if possible.

Regards,
        Daniel
