Hello

I have an use case where particular search operations on the same data in 1.2.5 and 1.2.11 differ significantly.

1.2.5 is on Centos 5.9 and 1.2.11 on Centos 5.11. I'm asking this as i'm in the middle of upgrade process and I come across this performance issue.

After feeding both versions with data from the same text dump, particular search operation takes 0.5s in 1.2.5 to complete whereas in 1.2.11 it takes 6s:

ldapsearch -D 'uid=root,ou=users,o=xxx' -x -b 'uid=someuser,dc=domain,dc=pl,o=xxx' -s subtree -w pass '(objectClass=someObjectClass)'

There is a set of 40 acls at the dc=pl,o=xxx node and 9 more on dc=domain,dc=pl,o=xxx. The acl allowing 'uid=root,ou=users,o=xxx' to access everything is at o=xxx.

I did already manage to figure out that the more acis i remove the shorter the search operation is. However even with those aci in place, search on 1.2.5 returns significantly faster.

I would like to ask if there are any factors that would make search operations longer while jumping from 1.2.5 to 1.2.11?
