Has anyone run across any good benchmarks or other research on tuning the ZFS recordsize when putting virtual disk files on it for a guest OS? I'm using VirtualBox at the moment. I have notice significant performance improvement when working with a DBMS by setting the ZFS recordsize to the same as the DB blocksize, so I'm guessing matching the blocksize of the guest filesystem would also be a good idea.
