in reply to No Performance gain with Parallel::ForkManager

OK, already mentioned by McA :-( but i would also give the old fashioned way a try:

my @mp3s = File::Find::Rule->file()
                           ->name( '*.mp3' )
                           ->in( $myMP3Library );

foreach my $mp3 ( @mp3s ) {
# doTheForkStuff...
}

Edit: Fixed tag.

And start with $MAX_PROCESSES = 10; or so.

    ++. Starting 50 processes for processing 100 files is most probably a bad idea in terms of performance (and actually most probably also for more files, but it is especially the case when each process will process only an average 2 files). I would also try with perhaps 10 processes, or maybe even only 5.
