--- Comment #53 from Roger Pau Monné <roy...@freebsd.org> ---
I'm attaching another patch that will allow to selectively disable some PV
optimizations, you will have to play with the following tunables, and see if
you can find which one(s) causes the VM to go faster:

hw.xen.disable_pv_ipi
hw.xen.disable_pv_et
hw.xen.disable_pv_tc
hw.xen.disable_pv_clk
hw.xen.disable_pv_disks
hw.xen.disable_pv_nics

Those tunables should be set in /boot/loader.conf, like:

hw.xen.disable_pv_ipi=1

Thanks, Roger.
