Finally, if you are going to do anything serious with OpenLDAP it has
been recommended repeatedly on this list that one should use the latest

instead of HDB/BDB

Not just "maybe". LMDB is about reliability too, not just performance. I justfound this presentation from http://wisdom.cs.wisc.edu/ testing software crashvulnerabilities. LMDB comes out with 0 silent data loss, 0 corruption issues.BerkeleyDB - multiple issues. (Prez from May 2014)

There are multiple reasons why OpenLDAP is abandoning BerkeleyDB. Performancewas only one of many.
