I've noticed others talking about it as well but none of them mentioned this kind of performance loss so I figured I'd ask about it. A lot of posts I was reading was saying to use disk shares instead. Unfortunately that's not a great solution even though you do get full speed. You either have to write to the array directly and suffer from parity speed penalty or write to the cache but the mover doesn't know where to move the file. I think it's kind of strange that the performance loss would be that large (over 20x loss). Do we know if there are any fixes in the works? For now my only solution is to fall back to using v6.3.

I upgraded to 6.9.2 and duplicated the problem. Diagnostics are attached. I did another copy of a 10GB (5,929 files) folder to a user share. The copy took more than 20 minutes after the upgrade. Before the upgrade the copy took 55 seconds. If I transfer the same folder as one file (7-Zip compressed as store), the file appears to transfer normally. nas-diagnostics-20211108-0949.zip

I've ran into an issue where User Shares are running extremely slowly after upgrading from 6.3.1 to 6.9.1. I'm running two cache disks. I have a user share setup to use the cache disks. If I copy many small files to the user share the transfer rate is less than 2MB/s. If I write directly to the cache drives via the disk share then the transfer rate saturates my gigabit network and runs about 110MB/s (~980Mbps). I downgraded Unraid and the speeds went back to normal. Just as a sanity check I upgraded to 6.9.1 again and the same thing happens so I was forced to downgrade again. Is anyone else experiencing this issue or does anyone have any idea what might be going on here?
