我正在运行CENTOS 6.3，并且PHP 5.4.9使用PHP FTP commands. 我正在使用它来将大文件从一个域上传到同一服务器上的 FTP 帐户。

我注意到即使是小文件的上传也需要很长时间才能上传：大约 10 到 15 秒。他们最终会上传。如果我使用相同的脚本上传到不同的服务器，它会快速上传：不到一秒钟。

我可以在不同的服务器上使用相同的 FTP 凭据，并且它们上传速度很快。为什么来自同一服务器上的一个域的 FTP 速度很慢？

用脚本更新：

$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
}

如果它们在同一台服务器上，为什么不直接复制文件而不是将它们发送出去，然后再将它们带回？我认为您正在使用出站和入站连接阻塞端口 21 (FTP)。

：：编辑：：

我知道这不是代码审查，但这里有一些小的改进：

$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 = $destination_path . $file_name;

$destination_path = $ftp_folder . $path;
$destination_file = $destination_path . $file_name;

     */ 
    $conn_id = ftp_connect($ftp_server) or die('Couldn\'t connect to ' . $ftp_server); # set up basic connection

    /**

     */
    $login_result = @ftp_login($conn_id, $ftp_user_name, $ftp_user_pass); # login with username and password
