I then restarted calibre in debug mode, it increased the db load time to a massive 6 seconds for 342MB and the total time from double-clicking on calibre to being at the GUI and ready to go to a massive 10.7 seconds.
Edit: extrapolating for your ~2,000,000 books, this would bring the database size to ~3.9GB (well below the SQLite maximum of ~140TB). I did some playing with various library sizes and reading the load time at startup seemed to be pretty much linear so that would take about 69 seconds to load so calibre would start in 73 seconds.

Not that many, about a quarter of that. You seem to be calling me a liar. Please, try it and see for yourself. Your math nonewithstanding, I stand as someone who actually has done it. You stand as someone who is guessing.

Sucks for you. I would never ever buy a Kobo. Ewww..

I bet you are. I'm surprised to hear that, I had no idea you would have issues with metadata and covers. What a dismal experience the e-book consumer game seems to be for most of you.

Perhaps that is why KOReader added the abiltiy to search the calibre database stored on the ereader....

I really don't see how that could be any more irrelevant to me. Please explain why that would matter to me? I use directory structure for both my ereader and my main library, with some post-processing to remove spaces for my ebook reader. I use the search functionality of my reader, I have to, I have over 30k books on it. However that doesn't take away from the value of having a directory structure. Its called the best of both worlds. A known, predictable structure that can be drilled down into at need and search functionality to find the things you want.

That's actually about right, with about .5 million sorted and deduped. Its' an ongoing process but I love it, so much fun. I'm not sure what the final number will be, I was loading everything into calibre and doing all my metadata type stuff just like you guys but I found a better way and I decided to blow my calibre library away and start over from scratch. I'm not sure what the exact number of sorted books is now since the reboot but I have started to load into calibre now so I'll be using that to remove foreign language books, merge and so on, however I will be keeping mulitple formats so that will skew the numbers.
I'll be happy to report on calibre's performance as I do so, with the caveant of Calibre having to deal with network traffic as it loads since I'm not maintaining two local copies.

I have a very well paying job and very few fiscal responsibilities.
As for finding the time, I subscribe to the "anti-library" approach.
I do collect from whatever sources I can, I am in progress building a book scanner for some very good 1920s engineering books I want to get into my library.
