New Photos App take a very long time to upload 20 Pictures, while the Activity Monitor is showing much more data sent (MB) than these two pictues

It can take days, even weeks.

Tell me 2 things and I will tell you the estimated upload time.

1 How big is your Library (in GB)

2 How fast is your upload speed.

Or you can just use the upload time calculator and do it yourself

You will see no coherent correlation while this is in progress, you may see none at all. stop watching the pot, it will boil when it is ready.

I am having this issue as well. I have over 100GB of photos uploading. I have the additional problem that it will not let me create a shared album. I am wondering if the updating must complete before it will allow me to create a shared folder. Does anyone know?

That's half of the information needed, how fast is your upload, that's the other half.

I have a 60 gbs internet service, but the status on photos preferences has said "updating" for almost a week. I can view my photos on my iMac but they still appear to be updating on my IOS devices. Does this mean they are still uploading to iCloud, and maybe why I can't create a shared file?

I do not believe that you have a 60Gb/s upload speed, or anywhere near that either.

Don't guess, measure it at speedof.me. Remember it is the upload speed we need, and that will be the slower of the two tests.

Ah yes, that's the download speed, upload speed is about 4 Bps.

Whoops, that's 4 mbps.

4 BPS?

Take a screenshot and let me see for myself.

Thats hundreds of thousands of times slower than the first speed you stated!

100Gb at 4Mb/s = 65 hours 44 minutes, best case.

Actually 65 hours is overly optimistic. The quoted speeds for upload are the raw wire speeds. However, all data sent needs to be placed in TCP packets, which are then encapsulated in IP packets. Best case for TCP/IP overhead is 2.5% (all packets maximum size, no retries), but remember that there are going to be a lot of partial packets, due to things like thumbnails and images not being exact multiples of packet payload size . (This is why Firewire 400 was always faster than USB 2, USB 2 was 480 Mb/s on the wire, but has a 30% overhead. Firewire 400 has only a 10% or less overhead and there are other factors that further improved Firewire performance.) There is also the unknown overhead for whatever protocol Photos uses to communicate with iCloud, which could easily add a significant overhead.

Then you need to add in congestion, changes in routes, lost packets, etc. Figure a minimum or 30% overhead for this sort of thing. A better estimate for your total upload would be 50% overhead, or about 90 hours to upload.
