I know this guides an I also read FAQs an Adminguide. dn2id plus
id2entry is a rule of thumb. If I calulate this like you told, its
approx the same size ...

loglevel is 0

I sent my first posting 2 days ago, but it did not reach the list ....
My second question is missing in the list till now.
So I sent them a second time, because I thought they got lost.
But what about the first part of my question. in this Posting. How

Does the slapd, search the whole database despite of indexes?
Thanks you very much
