One more piece of information. I was able to ascertain the slowdown happens only when ZFS is used heavily; meaning lots of inflight I/O. This morning when the system was quiet my writes to the /u099 filesystem was excellent and it has gone south like I reported earlier.
I am currently awaiting the completion of a write to /u099, well over 60 seconds. At the same time I was able create/save files in /u001 without any problems. The only difference between the /u001 and /u099 is the size of the filesystem (256GB vs 768GB). Per your suggestion I ran a 'zfs set' command and it completed after a wait of around 20 seconds while my file save from vi against /u099 is still pending!!!
