Slow initial uploads now?

I'm getting into self hosting and have gone through a few different installs of Immich as I learn my way around things. I just did a new build and currently doing the dreaded initial upload. In the previous times, I could watch as the files got uploaded very fast, until in got bottle necked. But this time while watching upload details there is a section called Downloading from iCloud and one called Uploads. Things don't seem to be getting bottle necked this time but because the Downloading from iCloud section takes so long for each file. I'm like 100 assets in in about 30 minutes. Does anyone know what this is for?
