When we initially configured a large (20TB) files server about 5

each zpool. Currently we have 17 zpools and about 280 datasets.
Nowhere near the 10,000+ you intend. We are moving _away_ from the
many dataset model to one zpool and one dataset. We are doing this for
the following reasons:
1. manageability
2. space management (we have wasted space in some pools while others
are starved)
3. tool speed
I do not have good numbers for time to do some of these operations
as we are down to under 200 datasets (1/3 of the way through the
migration to the new layout). I do have log entries that point to
about a minute to complete a `zfs list` operation.
It would be interesting to see if you still had issues (#3) with 1 pool and
your 280 datasets. It would definitely eliminate #2.
