Google Drive User Rate Limit Exceeded

Hi all,
I'm trying SmartFTP to upload all my files to Google Drive, but I'm getting a error message "User Rate Limit Exceeded" this always happens when I try to use more than 5 workers, threre is any where that I can increase the concurrent connections for Google Drive?

It's a server side (google) limitation.

There is any way to fix this? I have too much files to upload and its taking an eternity
