I too have heard that it is best to populate the tables (physical files) first, then add the logicals.
Some might suggest populating the tables in such a way that they are in order of the logical you need the best performance from. Or sorting them afterwards but prior to adding the logicals.
There are obscure little ditties to remember about logicals like adding them in an order where one can share the access path of another. For example if you have a logical by ColA, ColB, ColC and one by ColA, ColB then create the one with all three first.
Where clauses (select/omit in logical file terms) should be first in your sort order. For example: ActiveRecordCode, ItemNumber.
