Hello Team,

What are the various Tuning parameters that we should look at for performance tuning Openldap 2.4? 1. Indexing (See logs and find out if any unindexed searches, and index them as needed) 2. DB_CONFIG tuning various parameters such as cachesize etc

Anything else, please let me know.

First thing would be to establish which OpenLDAP backend you are using. If you are using a BDB based backend (back-bdb, back-hdb) then the first thing you need to do is migrate to the LMDB based backend, back-lmdb. That would be required prior to upgrading to OpenLDAP 2.5 or later, as well.

Beyond that, I would strongly advise reading the section on indexing in the OpenLDAP 2.5 admin guide. Indexing may or may not be beneficial depending on the specific use case.
