I can see also that you have lots of snapshots. I don't recommend using snapshots on the Transmission share. With CoW and snapshots if you make a huge number of in place modifications to files you will get a lot of fragmentation.

I can see you have high load on your NAS.

I would suggest that you backup your data, do a factory reset (wipes all data, settings, everything) and restore your data from backup.

We made some filesystem improvements (e.g. in 6.1.5), but some of these do require a factory reset if you wish to take advantage of them.

I would suggest after the factory reset that you leave Bitrot protection and snapshots off on the Transmission share.
