I can only comment on this question - you should not lose performance,
but you'll have more NAND flash space consumed by UBI for its own
purposes, comparing to what you'd have if you had sub-pages.

IOW, sub-pages are mostly lessening the UBI space overhead.

The MTD web page has a section about the space overhead with some more
information.
