</span>Oh my.<br>
<br>
I'd start pinging the illumos list on this. Also, are there any special tweaks you made in the 014 configuration? IF you did, I'd start back removing them and seeing what a default system does, just in case.<br>
<br>
I know Delphix and Nexenta still care about NFS quite a bit, so I can't believe something would be that bad.<br>
<br>
Maintainers: Check for NFS changes RIGHT AFTER 022 closed for blanket upstream pull-ins. Maybe it closed during a poor-performance window?<br>
