Lightroom CC: Why does it takes days, to upload 1000 raw files

Hi,
what is happening behind the scene, that RAW Files (42MP) are loaded into the cloud with a speed of approx. 10 pic/h?
- 50Mbit connection on a MacBook Pro.

Have a great day!

This is extremely unusual. Particularly with 50MB-connection.

Ya! I tested 42MP JPEG`s and they are loaded in seconds..

The answer depends on what kind of connection you are using. If you are on a cable system it is not uncommon to find the local drops to homes configured as a local area network through a server which connects to a trunk line. This means that the speed of everyone on the local network shares the bandwidth. The speed of the network is totally dependent on how many concurrent users are accessing the internet. If a lot of folks are streaming video or uploading stuff, the network slows down .


The other problem has to do with what kind of service you are subscribing to. Most consumer internet connections are asymmetric ; the download speed is usually the fast number you think you are getting. The upload speeds are generally much less. Only if you subscribe and pay higher charges do you get symmetrical service where upload and download speeds are the same. Even then you may not see the full speed you think you are paying for at certain times.


Ask your service provider what kind of connection you are using and you might be surprised at what you actually have.

Thanks for the insight.
You are absolute right, I should have mentioned the upload speed!

I tested the connection on a speedtest service. The speed should be very constant (fibreglass). 
The upload speed is 5 Mbit/s. Here the calculation I made:
(5 / 8) * 60 * 60 = 2.25 GB/h

The 1000 RAW Files are 35GB in total.
35 / 2.25 = 15h

Is this correct?

In fact: It already takes more than 24h to upload, with 600 pictures uploaded so far.

That is why I would like to know if there is anything else happening other than uploading. Any preprocessing?

Keep in mind that there is network overhead for sending the packets of data that have to be considered. All internet data is broken into packets that are sent and acknowledged between the sender, all intermediate relay servers, and the receiving server. That latency is sometime hard to predict depending on the circuits being used. It is a bit of a guess as to what effect that has on your upload speeds and depends on circuit bandwidths available.

I have a direct connect fiber optic feed to my isp from my home which is located about a quarter mile from their head-end servers. My connection is a symmetric gigabit. Even with this setup I have some longish uploads running on my cloud backups of terrabite size files for my law office backup. Even the raw photo files take time to upload at these speeds. Patience is necessary and I usually do massive uploads overnight and don’t worry about them.
