我将此脚本与 PHP5-CLI 一起使用，将文件从 Amazon S3 下载到 EC2 实例，但速度相当慢（160 MB 需要 1 分钟，大约 2 MB/s）。假设至少 10 MB/s 应该是可能的。我在代码中做错了吗？

require 'aws-sdk/sdk.class.php';

$s3 = new AmazonS3(array(
        'key' => '********',
        'secret' => '******************'
));
$s3->get_object('mahbucket', 'filename.tar.gz', array('fileDownload' => 'downloaded.tar.gz'));

存储桶在eu-west-1其中，实例在eu-west-1a

您的脚本看起来不错，但不久前我遇到了类似的问题，我无法解决......</p>

我的新方法是使用s3cmd在 S3 存储桶和我的 EC2 实例之间传输文件。您只需配置一次，然后就可以通过 PHP 触发它。它也更安全，因为您不必将 AWS 凭证存储在脚本中。

我认为速度还可以：
