OpenLDAP performance issues

[Bernhard Reiter]

Hi Dieter,

thanks a lot for your hints.
I am still lacking the right level to spin this problem away,
though. What would you suggest to get closer to the problem?
Try openldap 2.2.26?



[Can you also copy Steffen on suggestions as he mainly does
the Kolab-Server implementation. Thanks.]

It was _not_ disabled of course. 
Could a high number of checkpoint (like every 10 minutes) be a problem?
