Hello, I have migrated from HDB to MDB backend and I am seeing higher CPU usage on my MDB openldap consumers. openldap version 2.4.45 Syncrepl enabled (with a single openldap provider server which is also MDB and has no issues and no high cpu). The database has ~230K users. data.mdb is about 1.8G in size.
a) You need to be running a current release, not something 4.5 years old.
b) You need to be using delta-syncrepl with a current release, not standard syncrepl
c) Do you know what the server is doing to be using a significant amount of CPU? I.e., have you looked at what it's logging with stats + sync set?
The flags you're playing with generally can help in a high write environent, outside of that they don't do much. I certainly wouldn't expect them to affect CPU usage.
