What I mean is that if you have a broadband that is, for example 10/10 or 100/100
you will most probably get higher upload than download.
I can also draw a conclusion that apples servers has been under a lot of stress lately and this has probably been one of the main reasons for many of the issues we have noticed.
I have rarely gotten much more than 10mbps up to icloud for photos sync. We thought maybe icloud was doing some throttling as to not take 100% of my bandwith. but that is probably not the case because now, when my 200+ GB have been uploaded Photos is starting to download images from my other devices via icloud, and it is doing that at 100% of my capacity so at the moment a bit more than 100mbps.
So any direct or indirect throttling on the upload is most probably due to capacity at icloud.
I assume that once this service is running on a business as usual level. We will start to see much greater upload speeds. Apple has had the time to adjust available bandwidth based on the total customer base and most importantly everybody who has been waiting for this feature for months and began to upload their huge libraries almost at the same time have been managed.
Once working, once fully synced, this is a great feature that I have been waiting for a long time. Apple is most def make a lot of extra icloud storage cash. If apples icloud functions for "office-like-apps", mail and calendar etc was as good and accessible as googles I would have no issue with starting to use icloud for that too.
Personally I think it is much easier to get people to use icloud for photos backup and synching as well as iphone/ipad backup than it is to win the email and office-app war. The former generates much more data storage revenues and requires far less development.
sorry for going OT at the end...
