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
