更快Rackspace云上传

Question

我已经习惯了Rackspace API上传文件到RackSpace云。但是这种方法似乎有点慢。有更好还是更快的方式将文件上传到云（卷曲，http适配器等）？

我目前正在使用PHP上传并使用提供的API。

这里是我的解决方案如何使之快：

我上传用下面简单PHP脚本只丢失的文件。感谢它我只在一键点击而在几秒。

PHP源代码：

function UploadMissingFilesToRackFileCDN($file_paths_to_upload, $b_force_upload = false) 
{ 
    include_once("cloudfiles.php"); 

    // Connect to Rackspace 
    $username = cloudfile_username; // username 
    echo "Connecting to CDN..." . date("H:i:s") . "<br>"; ob_flush(); 
    $key = cloudfile_api_key; // api key 
    $auth = new CF_Authentication($username, $key); 
    $auth->authenticate(); 
    $conn = new CF_Connection($auth); 
    echo "&nbsp;&nbsp;&nbsp;&nbsp;Connected!" . date("H:i:s") . "<br>"; ob_flush(); 

    // Get the container we want to use 
    $container_name = 'vladonai';//'test_container'; 
    echo "Obtaining container $container_name..." . date("H:i:s") . "<br>"; ob_flush(); 
    $container = $conn->get_container($container_name);
