동일한 도메인에서 업로드 속도가 느림

Question

PHP FTP commands을 사용하여 CENTOS 6.3과 PHP 5.4.9을 실행 중입니다. 저는 한 도메인의 대용량 파일을 같은 서버의 FTP 계정으로 업로드하는 데이 방법을 사용하고 있습니다.

작은 파일도 업로드하는 데 시간이 오래 걸립니다. 약 10-15 초입니다. 그들은 결국 업로드합니다. 같은 스크립트를 사용하여 다른 서버에 업로드하면 초당 업로드 속도가 빨라집니다.

동일한 FTP 자격 증명을 다른 서버에서 사용할 수 있으며 빠르게 업로드됩니다. 같은 서버에있는 한 도메인의 FTP가 느린 이유는 무엇입니까?

는 스크립트를 사용하여 업데이트 : 그들은 동일한 서버에있는 경우

$ftp_server = "HOST NAME"; 
$ftp_user_name = "USERNAME"; 
$ftp_user_pass = "PASSWORD"; 
$ftp_folder = "/FTP DIRECTORY"; 
$path = "/testing/"; 
$file_name = $_FILES["theFile"]["name"]; 
$source_file = $_FILES["theFile"]["tmp_name"]; 
$destination_file = $ftp_folder.$path.$file_name; 
$destination_path = $ftp_folder.$path; 


function uploadFTP($ftp_server, $ftp_user_name, $ftp_user_pass, $source_file, $destination_file, $destination_path) { 
    $conn_id = @ftp_connect($ftp_server); // set up basic connection 
    $login_result = @ftp_login($conn_id, $ftp_user_name, $ftp_user_pass); // login with username and password 
    if ((!$conn_id) || (!$login_result)) { // check connection 
     return false; 
    } else { 
     $check = @ftp_chdir($conn_id, $destination_path); //check to see if folder is there 
     if ($check) { 
      $upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY); // upload the file 
      if (!$upload) { // check upload status 
       return false; 
      } else { 
       return true; 
      } 
     } else { 
      $check = @ftp_mkdir($conn_id, $destination_path); //make new folder 
      if ($check) { 
       $upload = @ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY); // upload the file 
       if (!$upload) { // check upload status 
        return false; 
       } else { 
        return true; 
       } 
      } else { 
       return false; 
      } 
     } 

    } 
    @ftp_close($conn_id); //close ftp 
}

, 왜 그냥 대신에 그들을 다시 복용 후, 그들을 밖으로 보내는 통해 파일을 복사하지? 아웃 바운드 및 인바운드 연결로 포트 21 (FTP)을 막히고 있다고 생각합니다.
