Hammer it.  Setup whatever requires the most timing, IAX, MOH, conference
bridge or whatever.

Setup SIPp (http://sipp.sourceforge.net/) to initiate x calls for the
duration and then you call in and see where it breaks.

Just to test the timing.

Piggy back a couple of quad pri systems and have them call each other and
SIPp into whatever app is most sensitive to timing.

what does cat /proc/interrupts show?

This is cool stuff, I will lab it up when I get some spare cycles.  I wonder
what happens with multiple VMs running Asterisk, I guess only one gets
access to the card, or it would be a mess.

Doesn't someone make a USB dongle for timing in VMs?  Anyone have input on
the best way get timing to multiple VMs.

I think it is time to start playing with Asterisk in various VM platforms
and configurations.  I want a stock underlying OS and stock guest OSes.

Xorcom has that USB FXX device.  Maybe a few of those, or multiple dongles.
Multiple FXX PCI cards with no modules assigned to different VMs?

Thanks,
Steve Totaro
