If you 1-sies your send, then it does this after each book.
Same behavior on my PW3/PW4 (metadata updated once per batch send).

That said, if one has 13,000 books on the device, I can understand how metadata update can take a very long time regardless considering how slow flash memory on SD cards and devices can be. Per robocopy, copy speed for my 500K-2MB books to a PW3 4GB is ~1-2MB/s. A bit faster on my 32GB Kindles.
