It might, because in an InnoDB table, your primary index also holds
your row data.  So it's actually your largest index.  A full scan of a
secondary index on your primary key may very well run faster than a
scan of the primary index itself, for the purposes of "SELECT
COUNT(*)".  Best way to find out is to try it :)
