jnikkir's library is OK in Safe Mode here - maybe a Win 10 v 11 thing.

I put the library on my 1TB internal SATA HDD - the VM switch times on the library (13 books and a single sort column) were laggy - much slower than VM switch times for bigger libraries with multiple sort columns on the same device.

But here's the rub, VM switching on jnikkir's library was also rattly - I could hear disk r/w heads moving - that's not happening on my bigger, and arguably more complex libraries.

On a whim, I put a copy of the library onto my 256GB SSD - result, VM switching near instantaneous. I admit that I've never been an SSD fan, not because there's anything wrong with them. But I'm not a speed freak and the claims for SSDs have IMO been over-hyped --- but this is the most dramatic effect I've seen from an SSD.

So, I tried moving the metadata.db file from the library folder on the rattly drive to the SSD and dropping a symlink to it in the library folder on the rattly drive. Guess what, less laggy and no rattling. Which seems to indicate that the disk I/O I can hear on the rattly drive is related to the metadata.db file - which surprises me.

I can't figure out why this tiddly little library should be rattling the disk drives cage but there's no doubt it is.
