To twenty books in a 24000+ book library I just :-
added four tags,
changed the publisher,
changed a custom date (last change date) and
changed a fixed value set custom column (status) which is shown in the tag browser
the spreadsheet was sorted on status (ascending) and last change date (descending), which is the default I have in View Manager, the tag browser was open with all categories collapsed, no virtual libraries or search terms were in effect, book details was displayed
Took < 7secs - I regard that as plenty good enough.
Sometimes I change the metadata on 100's of books, I can't recall any that were unacceptably slow, like more than few minutes. I rarely need to change author names or titles - I try to ensure they are correct before I move the books from my 'new books' library to my 'main' library.
I do not have any columns derived/calculated from other columns, nor do I have coloured columns, or other decorative effects, and I don't use the cover browser - i.e as vanilla as it comes.
My calibre system has an i5 processor with 6GB RAM. The library is on a WD 2TB internal spinning disk, on a SATA controller, its formatted for NTFS, and the drive is fully indexed for Windows search and Locate 32. I don't use an SSD, or RAM Disks or any of that tricky stuff. The database is in the library folder with the author & book folders and its 109MB.
The software and config data are on another 2TB WD drive.
