May not be really efficient, but I would first try creating multiple pdf
files (as large as you can) using FPDI (http://fpdi.setasign.de/)

Store the file names into an array as you are doing this, then try
something like:

require('fpdi.php');

class concat_pdf extends fpdi {
    var $files = array();

    function concat_pdf($orientation='P',$unit='mm',$format='A4') {
        parent::fpdi($orientation,$unit,$format);
    }

    function set_files($files) {
        $this->files = $files;
    }

    function concat() {
        foreach($this->files AS $file) {
            $pagecount = $this->setSourceFile($file);
            for ($i = 1; $i <= $pagecount; $i++) {
                 $tplidx = $this->ImportPage($i);
                 $this->AddPage();
                 $this->useTemplate($tplidx);
            }
        }
    }

}

$pdf= new concat_pdf();
$pdf->set_files($file_list);
$pdf->concat();
$pdf->Output($outputname,'I');
