Red Hat Directory Server slow modification of members in large groups or large quantities of multi-valued attribute values

Solution Verified - Updated -

Issue

We have large groups in our LDAP directory with more than 300000 members.
We already made some cache tuning.
Each modification of the group members is slow, it can take 20 minutes to add 10000 members.
During this operation, the LDAP server use 100% CPU taken by one thread, and has no wait IO.
