Description

FreeBSD brings the pvclock module. According to https://lists.freebsd.org/pipermail/freebsd-arch/2015-January/016587.html using a paravirtualized clocksource can save unneccessary VM exists and improve performance in some workloads. In the forums (https://forum.pfsense.org/index.php?topic=109071.0) it was suggested that the module will ship with pfsense 2.4. A current beta install shows no signs of it.

  1. cd /boot/kernel
  2. ls -al pvclock*
    ls: No match.
  3. kldload pvclock
    kldload: can't load pvclock: No such file or directory

Even it won't be enabled by default the module should be available with pfsense 2.4 supporting KVM installs.

pvclock is not a module, it's a standard piece of the kernel as you can see at original review at https://reviews.freebsd.org/D1429
