> To process collectiveAttributes, the service does a lookup searcing for the "collectiveAttributeSubentries" operational attribute. This lookup cost around 17% of the global search time, and can be avoided, as we can add this attribute to the list of returned attribute in the original lookup, instead of doing a specific lookup for this attribute.
> We have two cases :
> - the "collectiveAttributeSubentries" does not exist : net gain will be 17%
> - the "collectiveAttributeSubentries" exists : we will have to remove it from the entry and process the collective attributes to add them to the entry. The gain will still be enormous (less than 17%, but very close)
> In the second case, we will just have to be sure to return this attrinute to the user who has specifically requested it into the original search request.
> The gain will be major.
