Lightroom Classic 7.0.1: Importing Images Slow

Importing in Lightroom Classic CC has serious issues. It seems it may be related to large catalogs. Import is slow and only shows a few thumbnails and files at a time as it's importing into current import. It is slowing down everything else in LR with significant delays.

The reason I think it may be due to large catalogs is one, I had a hell of a time upgrading my catalog initially from Version 6.12 and it took 24 hours to complete that. Others with small catalogs had no issues and it went quickly. So I think LR CC Classic does not like large catalogs (mine has 440,000 images in it and is 12 GB). So I tried something new which was to create a new catalog. I noticed that catalog was speedy at first when I imported a couple folders of images, like really really speedy. Next, I imported the 440,000 images from my older LR CC Classic catalog into the new one I just created thinking I was in the clear (that took 24 hours as well btw) and now I'm back to incredibly sluggish import again with the newly created catalog.

C'mon Adobe I'm happy to pay your subscription fees, but just give us software that's been well tested before releasing without these and all the other issues I'm reading about on the community feedback pages. This is beta bug stuff and should have been squashed well before official release. And while I'm feeling angry, the whole naming convention with Lightroom CC, Lightroom CC Classic, etc is just plain BAD! It adds unnecessary confusion and makes Googling problems that much more difficult to wade through new vs. old versions.
