If this is a new index, it's possible that you don't have anything to index yet

You probably don't ever need to worry about optimizing given the expected size
of your index, We'll be depreciating the optimize method in 3.6.

The generics branch is really the same as 2.9.4, except of course we've tried
to use generics (such as List<T> etc).
