 Description   

If you want to do a: find on A, return ABC using an index on ABC, there is no need for the server to bother sorting BC on insert/deletes

this could provide quite a performance boost and could be an option when you run ensureindex ?

The performance difference is going to be very minimal relative to other aspects.
