--- Comment #4 from Jonathan Druart <jonathan.druart at bugs.koha-community.org> ---
Quick benchmark using: 

use Koha::Biblioitems;
my @record_ids;
my $biblioitems = Koha::Biblioitems->search( {}, { join => 'items', columns =>
'biblionumber' } );
while ( my $biblioitem = $biblioitems->next ) {
    push @record_ids, $biblioitem->biblionumber;
}

and

use Koha::Biblioitems;
my @record_ids;
my $biblioitems = Koha::Biblioitems->search( {}, { join => 'items' } );
while ( my $biblioitem = $biblioitems->next ) {
    push @record_ids, $biblioitem->biblionumber;
}

gives 1.4s vs 1.7s with 8600 items.
