I agree with you Constantin that the sync is a performance problem, in the same way i think in a NFS environment it is just *required*. If the sync can be relaxed in a "specific NFS environment", my first opinion is that the NFS is not necessary on that environment in first place. IMHO a protocol like iSCSI would have a much better performance in such situation, at least would be no caution to handle the consistency between other clients. That said, options are always good, and have the possibility to disable the ZIL per filesystem is more one *gun* in the world. And as always, can reach the cops and the bad guys. Keep in mind that JB is trying to send to jail who is winning performance benchs without syncing to disks. ;-) Keep the good work in your blog!
