My computer has a SSHD with 16MG RAM but even just copying a book from anther library takes a lot longer than it used to.

I really don't want to split up the library physically, but if I were to use virtual libraries only showing specific columns would it run faster?
5,000 books is not many books, I have a library with 150,000

60+ columns seems excessive, especially if the library contains actual ebooks rather than 'foreign objects' such as music or movies. Composed columns (columns built from other columns) can have a -ve effect on performance

45 plugins seems excessive, although they should only effect start up times, but I would get rid of any I don't actually use.

60 icon rules also seems excessive, maybe you could reduce the number of rules by using Program Mode templates.

As has already been mentioned, use the View Manager (VM) plugin to limit what columns are shown in the Book List. VM will also define the sort order.

Regarding AntiVirus (AV): IMO if you need to exclude your calibre library from the AV you use, you need to get another AV. I run two, Defender and MalwareBytes, I exclude 1 DLL (a Word Addin) in MWB, and nothing in Defender. As far as I'm concerned tey have no discernible effect of calibre performance.

Added: Copying a typical book (1 cover, 1 PDF, 1 DOCX, 1 EPUB, 1 metadata.db) from my Intake library to my Books library takes a second or two, copying a 'book' which has audio/video content (FLAC, MP3/4) or hi-res comics (CBZ) take longer of course. The libraries are on a SATA 3.0 2TB HDD.
