      Xen 4.0 did some changes to the tick tack machinery for Dom0/U

      I see that a default installation of Bookworm default to a clocksource set to xen, this is not good for some or actually most of the applications run today, latency increase and increased load.

      Changing clocksource to TSC might be a better option or is it? i have been using TSC for some time with much better latency and performance results

          What latency are you referring to?
