Berend> 1. Does not effect nfs3.
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.

All the best,
