Hmm, I expected that it would only take hours with your build.
I guess the IBD was mostly limited by internet speed. Google's first link is
their legal disclaimer:
Starlink users typically experience download speeds between 25 and 220 Mbps
It's unfair how it's advertised to OP with "
150-200Mbps download" while their legal document indicates that it's typically within that range.
Anyways, 25Mbps (
about 3MBps) isn't too bad for IBD, unless its bandwidth is used by other processes and devices.
