Sorry, I failed to specify that that is the upload speed! I used a speed test website to verify. All my other images upload reasonably fast, but these RAW images... man, it's like one every hour. I don't know what's happening.You may have 250 Mbps for your download speed but what’s your upload speed?
I’ve got 100 Mbps myself but my upload is only 5 Mbps.

On a good day, 250 up, 250 down. But, on not so good days, maybe 150 down. I'm in Salt Lake City, Utah. I think Apple has a data center in Oregon, if I'm not mistaken. I suppose I could call up my ISP and get some insight from them. When you say you're getting 45-50 per hour, are those RAW format images?Seriously? What's your downlink speed?
Anyways, keeping focus;
There are many links in the chain of networking. Whilst 10 in a day sounds extremely low, you may be very far from an Apple Data center, your ISP may give low priority to that connection, Apple may not have allocated a lot of resources to that part of iCloud for your area due to low demand, there could be high traffic on the server setup these days and so on.
But I certainly get better results than that, though I wouldn't call it fast. I can probably do 50 in an hour. Still not fast, but significantly faster. And my upload speed is around 45-50.
You need to divide by 8 to get a proper comparison if 100 from ISP it is 12.5 in iStat.
iStat can be set to B or b. So it's not necessarily a case of dividing by 8 - check the settings.
That does slow the process down. I ended up - when I got the new 2019 iMac and discovered that Photos was running MUCH slower on it than my 2015 iMac - getting an external SSD drive and VIOLA, everything sped up dramatically, including uploads.I wonder if the stall has to do with the fact that I'm running my library from an external hard drive?
