Hi!

 The kernel shipped by Citrix for Debian via xen-tools are configured with CONFIG_HZ_100=y, but the Debian kernels and my custom kernels are configured for CONFIG_HZ_250=y or even CONFIG_HZ_1000=y.

 So, what is the impact of this clock to a Xen system?

 Which option is more suitable for Xen systems?

Regards,
Thiago
