我们正在尝试从GCP存储桶控制台下载文件，但是性能确实很慢。即使是一个50 MB的文件，也要花费大约2到3分钟的时间，而且变化范围也很大。我们正在使用storageclient downloadobjects方法

我们有一个适用于GCP上传的代码，该代码可以更快地上传GB的文件。在下载方面是否存在特定问题。

我们正在使用C＃代码进行上传和下载。

class Program
{
    public static void Main(string[] args)
    {
        GoogleCredentials gcpCreds = new GoogleCredentials()
        {
            private_key = "-----BEGIN PRIVATE KEY-----PrivateKey-----END PRIVATE KEY-----\n",client_email = "client_email",type = "service_account"
        };

        var credentials = GoogleCredential.FromJson(JsonConvert.SerializeObject(gcpCreds));

        // var credentials= GoogleCredential.GetapplicationDefault();
        var storage = Storageclient.CreateAsync(credentials).Result;
        string localPath,directoryPath,localFileName,objectname,bucketName;
        directoryPath = "localpathstring";
        objectname = "SourceFileName";
        localFileName = objectname;
        localPath = directoryPath + "\\" + localFileName;
       bucketName="bucketName";

       FileStream fs = new FileStream(localPath,FileMode.OpenOrCreate);

        //Code to download with progress bar
        DownloadObjectOptions option = new DownloadObjectOptions();
        using (fs)
        {
            var progress = new Progress<IDownloadProgress>(
                 p => Console.WriteLine($"bytes: {p.BytesDownloaded},status: {p.Status},"));
            storage.DownloadObject(bucketName,fs,option,progress);
            }
     }
