Ditto, and also some estimate of when we can see them in opensolaris.

[zfs-discuss] CR#6850837 "libshare enhancements to address performance and scalability"

[Paul B. Henson]

I've had a case open for a year or so now regarding the inefficiencies of
having a large number of zfs filesystems, in particular how long it takes
to share/unshare them (resulting in a reboot cycle time on my x4500 with
8000 file systems of over two hours).

I got an update indicating that the subject mentioned bugfix was going to
resolve this, but that they did not plan to back port it to Solaris 10.
They also were not able to provide any technical details of what was fixed
or how much the performance might improve.

Would anyone happen to have any details of what changes were made, what
kind of improvements might be expected, and why it's not going to be
feasible to backport that change to Solaris 10?

Thanks...
