Hi Florido, all,
[...] 5) ldap-add new objects -- which boils down to ldap-adding a whole new LDIF document (that is, the entire DB) in most of the cases due to -- guess what -- CrationTime and Validity which are always changing!!! :D
If that were true, we would not have abandoned the old method: populate a fresh DB in the background, switch when it is ready.
Good to know then! I cannot tell how much is ldapadded, I speak for what I've seen running a top-bdii myself testing the data I produce with ARC, for sure all our records end up being added again due to timestamp change. But you guys did the benchmarks, you know better, and you don't aggregate only ARC stuff, so I blindly trust you. As I said I am not a BDII developer! As I said already, there's a lot of very smart ideas on how BDII works wrt performance.
