Hi Willem,

  You'll most likely want to keep some memory and processor resources 
available for the host system. ZFS will need memory for ARC and CPU for 
operations - if these aren't available, it will compete with bhyve's use 
of CPUs, and there will be times when these are conflicting.

later,

Peter.
