下载大文件时，GuzzleHttp客户端非常缓慢

I'm trying to download a file from a server using GuzzleHttp client. but it turns out to be so slow. When I use the download link with a client like IDM or Aria2 its upto 2MB/sec. But when using Guzzle it's about 100KB/sec Here's the code

$client = new GuzzleHttp\Client();
$sink = "path/to/sink";
$client ->get($url,[
    'sink'=>$sink,
    'progress'=>function($size,$dl,$up,$upt){
         echo "$dl/$size 
";
    },
  ]);

How can I speed up the download process?

I've to use Guzzle because it's required by the Application I'm working on
