--- Comment #4 from Peter Grehan <grehan@FreeBSD.org> ---
Single vCPU guests perform very well in oversubscribed environments since there
are no lock-spins against other possibly de-scheduled vCPUs. However, you still
may hit the ZFS memory competition issue. Note that you can set the ARC-max on
the fly in 11.1 and avoid the reboot, using the vfs.zfs.arc_max sysctl var. ZFS
should slowly drop down to this value if it is above it.

>not sure if you want to mark the bug as closed

Fine to keep this open until the issue is resolved.
