OK - so not fillfactor and not some unicode-related padding. I can't see
how a 32 vs 64-bit architecture change could produce anything like a
doubling of database size.
Is it that each file is doubled in size, or are some much larger while
others are about the same? If the indexes are to blame it's presumably
something to do with the order of row access during index creation.
