I've done a not too scientific test on reboot times for Solaris 10 vs 11 with regard to many filesystems...
http://www8.cs.umu.se/~stric/tmp/zfs-many.png As the picture shows, don't try 10000 filesystems with nfs on sol10. Creating more filesystems gets slower and slower the more you have as well.
Since all filesystem would be shared via NFS, this clearly is a nogo :). Thanks!
On a different setup, we have about 750 datasets where we would like to use a single recursive snapshot, but when doing that all file access will be frozen for varying amounts of time
What version of ZFS are you using? Like Matthew Ahrens said: version 27 has a fix for this.
