I'm getting an array reference from DBI like this:

my $arrayRef = $sth->fetchall_arrayref;

I want to find the number of rows returned, how do I do this?

I know I could do $sth->rows and get it but I'd be doing it over 600,000 times and don't want to add the extra stuff to the DB, just counting the array's in my array ref would do better.
