with db_verify once upon a time...

One thing to test would be performance on queries with the search base different from the database suffix. If you see the problem I thought I was seeing, hdb will be an order of magnitude worse in this case. That was with an older version, 2.2.17 I think, and of course the usual caveats with respect to tuning parameters.
