Given my conversation with blair on this subject earlier today, I imagine he's referring to starting on grouper API changes that would support faster selection of groups to be provisioned. We looked at two such scenarios, and in one a minor change to ldappc code would also be needed.

Good material to discuss next week.

I'm pleased to see prospects for making substantial performance improvements start to emerge already!

However, my sense is that the algorithm that ldappc uses to maintain
the membership of these groups -- when a run includes a number of
membership changes -- may be less than optimal....

I haven't looked into that part of the Ldappc code yet, or really any
part that touches LDAP, but I have spotted some areas where between
some tweaks to Ldappc and the Grouper API we *should* be able to
improve its performance when interacting with the Grouper API fairly
significantly. I think I'll be able to start working on those code
changes next week.
