IO performance?
I tune it down (from FreeBSD's default of 1000) in order to reduce the
amount of CPU being used by the various timer interrupts when VMs are
[otherwise] idle.
IIRC DragonFlyBSD has HZ=100 by default and at some point FreeBSD
started detecting that it's being virtualized and tuning HZ down
without the user having to do it in /boot/loader.conf
