Taking a long time to shut down is one of the symptoms of an unnecessarily huge metadata.db. You may have one or more metadata.db files that are mostly unrecovered SQLite dead space, causing the "real data" to take up just a few percentage points of the "physical data" file size.

Run Job Spy > Utilities > Vacuum/Compress metadata.db En Masse [All Other Calibre Libraries].

Then, run Calibre's 'Check Library' for the current Library to compress it.

Then, "trim" your SSDs and defrag your HDs.
