Back in the days of OpenLDAP 2.1 with Berkeley DB 220.127.116.11 we used to have to
'reload' out backend database occasionally as non-indexed reads would get
slower and slower over time. The 'reload' entailed:
* stop slapd
* slapcat the contents to an .ldif file
* remove the database files
* slapadd the .ldif file to create a new, fresh db instance
* start slapd
Then our performance problems went away. Re-indexing didn't do the trick.
Is such occasional re-building of the backend database recommended in OpenLDAP
2.4.25 with Berkeley DB 4.8.30?
Try it and see.
Non-indexed reads are always going to be pretty slow, regardless.
Might be that he's hitting this?
Clearly not, since that message is all about indexing, and he's talking about
