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.
