It’s, Bruce! With the release Windows Server 2012 we all have to start learning the new features of the product. It is Friday night and I studying Deferred Index Creation. Below are some resources to bring you to speed at the same time.
This new feature solves the problem of ALL DC in a forest at the same time getting bogged down after you enable indexing on attribute’s in AD.
Deferred Index Creation

In the past, index creation could adversely impact domain controller performance. Windows Server 2012 introduces a new capability that allows forest administrators to defer index creation to a point in time they choose. By default, domain controllers create indices when they receive the appropriate schema change through replication. In Windows Server 2012, a new DSheuristic was introduced to control whether or not domain controllers defer index creation.

I guess this is especially important for larger organizations. I am assuming this is not a huge deal for small or medium Forests.
Correct. This tends to be a large organization issue. Or when you have hardware that is not sized correctly.
