If I were you, I'd modify the arrayref sub and not throw away the return value. It's hard to say what kind of optimizing Perl does with fetchrow_arrayref() in void context:

while (my $arr_ref = $sth->fetchrow_arrayref(\@result)) {}

For what it's worth, www.perl.com has a recent article about various tricks to make it easier to use DBI.
