I would expect eval to be a little slower, but not that much. Maybe this is because of the extra scope you're adding here. Try changing the no_eval_code to this, to see if the extra scoping is free or not: 
sub no_eval_code {
    for (reverse 0..9) {
        if ($_==0) {
            error_sub();
        }
        else {
            {
                my $x = 100/$_;
            }
        }
    }
}
