Creating Zip file in Azure

Hi...

I want to create zip file in Azure.... I am having more than 200 files in that zip file ....  But it is taking more time to upload zip file into Azure....

I m having the below code ...

              using (var zipStream = new MemoryStream())
                {
                    zipFile.Save(zipStream);
                    zipStream.Seek(0, SeekOrigin.Begin);
                    var blobRef = BlobStorage.GetContainer().GetBlobReference("_Files.zip");
                    string Urlblob = blobRef.Uri.ToString();
                    blobRef.UploadFromStream(zipStream);
                }

........... Can any one help how to increase the speed to upload it into azure

Thanks,

Malar
