I use HZ=100 and the preemption options turned off. I have no measurements to 
back this up but from memory I have been happier with these setting compared to 
other HZ values and/or preemption turned on.

I have been wondering what HZ values and preemption settings others have been 
using with linuxpps and whether there has been much difference between the 
various settings.

I have noticed on comp.protocols.time.ntp if you mention HZ other than 100 and 
linux you get told to try HZ=100.
