I know nodepool keeps a number of instances up and available for use, but
on FN it was usually tapped to the max so I am not sure this logic applies.

Anyways in my performance testing and tuning of Openstack to get it moving
as fast as possible, my determination was local NVME storage fit the
rapid fire use case the best.  Next best was on shared NVME storage via
ISCSI using cinder caching.
