And i take off facebook XHPROF from index.php files.

handle()->getContent();

} catch (\Exception $e) {
    echo $e->getMessage();
}

////end of facebook XHPROF
//$xhprof_data = xhprof_disable();
//$XHPROF_ROOT = __DIR__ . " /../../www/";
//include_once $XHPROF_ROOT . "/xhprof_lib/utils/xhprof_lib.php";
//include_once $XHPROF_ROOT . "/xhprof_lib/utils/xhprof_runs.php";
//
//$xhprof_runs = new XHProfRuns_Default();
//$run_id = $xhprof_runs->save_run($xhprof_data, "xhprof_testing");
//
//echo "http://localhost/xhprof_html/index.php?run={$run_id}&source=xhprof_testing\n";

Using apache AB tools benchmark it.

it only “Requests per second: 311.85 [#/sec] (mean)” we lose 1000% speed.
