Is there a reason why OpenLDAP does not seem to use more than 8 cores regardless of the number of threads it is being told to use? With 16 threads it saturates 8 cores, 16 threads and 16 cores still uses 8 cores, 32 threads and 16 cores... only 8 cores are used.

Can you offer any guidance? Thanks.
The OpenLDAP 2.4.44 release is over 4 years old.
You need to:
a) Upgrade to a current release b) Migrate off of the back-bdb/hdb backend it seems like is being used to back-mdb. They are deprecated and have serious performance issues vs back-mdb (< https://mishikal.wordpress.com/2013/05/16/openldap-a-comparison-of-back-mdb-...
).
If you are using RHEL7 or RHEL8, my company provides a free drop-in replacement:
