I would like to find all directories which contain a specific file. Until now, we used the following idea: 
find( sub { get_dirs( \@list_of_dirs, $_ ) }, $root_path);

sub get_dirs {
    my ($dirs_aref, $current_path) = @_;
    my $abs_path = abs_path($current_path);
    my $file = $abs_path."/"."secret.file";
    my $ignore_file = $abs_path."/".".ignore";
    push (@{$dirs_aref},$abs_path) if((-e $file) && !(-e $ignore_file)
+);
}

The problem is that finding over a large directory could take hours. I'm trying the reduce the waiting time.
My first idea was to split the directories into the process so they will perform a parallel search but I'm not sure if that a good idea.
Is it possible to suggest a better idea?
