@KC_20CY Just curious, how can you have so many tags? 11k is enormous. Have you created them all by hand? UPDATE The answer is in your initial post, you use Tabbles app.
Don't you have performance issues when browsing so many tags?
Also I noted you are using Dropbox. In my experience the sync with Dropbox takes forever for large number of notes (11k in my case, 27k in yours). How long was the initial sync for you? Have you synced any new device recently, how was it?
I found Joplin Cloud 10X faster than Dropbox for my 11k notes. More details: How to survive with a large dataset on Joplin (10k notes, 20k resources, 10GB)
Your dataset size is impressive in all dimensions (notes, folders, tags, notetags) which makes it very interesting as it pushes performance to the extreme. Have you ever tried to sync to any mobile device? I assume you are only using your Desktop app.
