iCloud photo library upload slow on new Macbook (2 weeks to upload 6,000 out of 30,000) pictures).

I have a very good internet upload speed and connection. When I turned on iCloud photo library upload to sync my photos across all of my devices, it started to download photos right away, but at a snail's pace. It has been two weeks since turning on iCloud photo library and only 6,000 of my 30,000 photos have transferred to iCloud. Is there any way to make this faster????
