Really slow download of photos from iCloud on Macbook

Hello,

I tried to find related topics, but I've only found some about uploading speed issues.

I have a MacBook Pro (Retina, 13-inch, Early 2015) running OS X (El Capitain) - Version 10.11.13 and in my last trip I took about 1400 photos using my iPhone.

When I got home and turned on my MacBook, it started syncing all photos (all photos were uploaded successfully from the iPhone) and did not finish yet... it's been 3 days already.

Check my internet speed and everything is fine...

Could you guys help me figure out what is happening? Did someone experience the same?

Thanks

Wilson
