One update: with zfs sync=standard, I can get nfs3 to perform as bad
as the nfs4+patch.

1. without nolock, without async, sync=standard: 8m21s

2. with nolock, without async, sync=standard: 5m37s

3. without nolock, with async, sync=standard: 4m56s.

4. with nolock, with async, sync=standard: 4m23s.

5. without nolock, without async, sync=disabled: 1m57.


PS: the nfs4 test was done with sync=disabled.
