Hello,

The XEN kernel in "XEN RELEASE-4.0.1" is shipped with the following
config parameters:

CONFIG_HZ_1000=y
CONFIG_HZ=1000

At many blogs and forums there is a discussion that the CONFIG_HZ
parameter should be changed to 250 HZ or 300 HZ.

We will operate a DomU and the Dom0 with the same 1000HZ Kernel. Is this
setup possible and recommended. How high is the performance cut-off?

Which option is more suitable for Xen systems?


Thanks,

Christian
