Interesting. On Windows I started experiencing long startup times starting sometime in the last 90 days. I've got about 5K books, and the FIRST startup takes about 2 minutes, with the "Starting up, please wait...\n\nStarting calibre: loading books..." banner staying onscreen the whole time. If I immediately exit and restart the app when it finally comes up it launches in < 2 seconds. If I go to Task Manager during the long startup I see two threads running: "The main calibre program" and "calibre worker process". If I terminate that latter BEFORE calibre fully loads and then restart calibre, that ALSO results in a quick start.

I don't know how long the "loads quickly after sitting through a long start" behavior lasts. At some point, after being unloaded for an indeterminate period of time, the slow start behavior returns. (For example, if I unload it and go away for several hours before trying to restart then I again have to wait 2+ minutes for restart to complete.)

Currently on 8.14, and this long restart behavior started happening at some point in the 8.x series, but not certain when. Did not exist more than 3 months ago, however, fwiw.
