Nevermind slowness has returned...
However I found a log in event viewer when I restarted a bunch yesterday: SQLite Error 8: 'attempt to write a readonly database'.
Which led me to this post: https://forum.jellyfin.org/t-sqlite-erro...y-database
I have restarted Jellyfin running it as admin and speeds are back to normal.
I wonder if the way I stop Jellyfin and restart it for backup may have tangled permissions or something but I will keep digging that way.
