I compiled my own kernels for c4 and c5 that dropped the HZ down to 100.  For 
me, it's a big improvement, especially when it comes to keeping the clock 
correct in the vm.  And yes, performance is slightly better, because the vms 
aren't killing the hardware with unnecessary cpu usage trying to process all 
those ticks.

Thanks for the kernels.  Hopefully they will be eventually added to the 
centosplus repos.

Very interesting.  Wasn't aware of that.  Thanks for posting.  Have you
noticed tangible differences when running stock vs the kernels
mentioned there?
