Similarly, I have three 'real' libraries - Texts [150,000+], Media [8,000] (audio and video broad/pod-casts), and Periodicals [6000]. They have different custom columns, and the Media and Periodicals libraries use the Title and Author columns 'perversely'. I also have an Intake, and a Resolution (a parking bay for duplicates etc) library. The numbers in [] are approximate number of books.

Memory seems to be what calibre likes most. 64bit Win 7 Pro can address up to 192GB, but I have a gut feeling there's a practical limit of 32GB, assuming you can even physically cram that much onto your mobo.

My rig is an i7 with 16GB of RAM, a 256GB NVMe SSD system drive, running Windows 10 Pro 1803. My libraries are on an internal 4TB SATA3 drive. Calibre starts in < 10 seconds irrespective of which library it's opening.

I got this system in August 2017, prior to that I had an i5 with 6GB of RAM, 128GB SATA2 SSD system drive, and 2TB SATA2 data drive, with Win7 Pro. At that time my Texts library had about 120,000 books. And calibre start-up times were more or less the same as they are now.

I'm with you on the 'will I live that long' question. I had to get a new system because my old one had persistent problems that seemed to emanate from the mobo, three video cards and a memory stick 'blew up' over a couple of years.

You could try using the Consolidate All Library Metadata plugin to test out using a single library.

BTW I run 2AVs, Defender and MWB; two content indexers Windows (docx, epub, pdf) and X1 (docx and pdf); and Windows File History. IMO they have no discernible affect on calibre performance, on this rig or the previous one.
