I would recommend using a DB_CONFIG file during the slapadd that turned
off the writing the db after every transaction (I'm at home, and don't
remember the command) to speed up the bdb.

Of course, IMHO, backend bdb isn't ready to be the production backend.
There's no documentation on how to maintain it in the administrator's
guide (or wasn't at my last reading).  You have to go read the C
programmers reference material on sleepycat and extrapolate to the
commands you would want to run on a regular basis.  Further, the
developer's list still is talking about bugs and changes to the
operation of bdb (granted there are still bugs in the ldbm code).
