How long should it take to upload 50Gb of photos into iCloud ?

I've been watching my photo library slowly uploading into iCloud via the new 'photos' app but it is taking forever. The upload is taking approx 2 photos per hour. At this rate it will take months. Am I doing something wrong ?

MacBook Pro, OS X Mountain Lion (10.8.4)

No. Wi-Fi is slow. If you are using an 802.11 n capable network you can upload files as fast as your ISP permits. For example, if your upload limit is 512 Kb/s - 64 KB/s or around 228 MB/hr. That means it will take around 4 hours for 1 GB. So, 50 GBs may take around 200 hours - nearly 10 days. That is theoretical. It can take much longer in reality. The faster your ISPs upload rate is the less time it will take.

What % overhead are you using


I just made a simple calculation from the given speed to the 50GB. Obviously in practice it's going to be a lot longer than that. (Actually in practice it's unlikely to work at all, at least as a single upload).

In practice the encoding allows for 8 bits of data in every 10, this would be excluding any other bits to indicate end of file etc. 20% is a minimum for most types of file transfer over the internet.


It really doesn't matter that much though, sub 5Mb/s connections and Gigabytes of files will make for a long long upload. I just wish more users were aware of that.
