Seems strange to store 1 million objects in an ordered container.
The use case for Ordered Container is for user-sorted content.
I am skeptical about a user sorting 1 million objects.

IOW, I would not care of performance when I use OrderedContainer because 
it would hold human manageable number of objects.

OTOH, if I would need to present 1 million objects, I'd sort them only 
at presentation time based on correct filters.
