Description 
While doing other performance testing, I noticed that the time
it takes to create a filesystem is dependent on the number of
properties specified at create time.  For example:

# ptime zfs create pool/foo
real        1.262
user        0.017
sys         0.026
# ptime zfs create -o compression=on pool/foo
real        1.890
user        0.017
sys         0.026
# ptime zfs create -o compression=on -o checksum=off pool/foo
real        2.440
user        0.017
sys         0.027
# ptime zfs create -o compression=on -o checksum=off -o readonly=on pool/foo
real        2.879
user        0.017
sys         0.026
