Getting CloudBlobDirectory size without doing a listBlob

I am trying to see if there is a more efficient way to get the size of CloudBlobDirectory (including the CloudBlobs within it). I am seeing listBlobs() along with "blob.downloadAttributes()" for each blob take 10-15 minutes for ~10,000 blobs. This is what I am doing currently:

        for (ListBlobItem blobItem : azAccount.getContainer().listBlobs(path)) {
            if (blobItem instanceof CloudBlob) {
                CloudBlob blob = (CloudBlob) blobItem;
                blob.downloadAttributes();
                totalSize += blob.getProperties().getLength();
            }
        }

Is there a faster way to do this?

You don't need to do the additional downloadAttributes. If you simply delete that line, I think you'll see it works. ListBlobs populates the content length property for the blobs it returns.
