December 15, 2025Dec 15 Hello,I am fairly new to Unraid and have been having a performance issue with my setup.Problem:When using ARR's/SABNZBD to find linux distro's, I have what I believe is a read/write issue. I can watch the file being downloaded which will go to RAM first, once the ram is full it will dump to my SSD cache drive. When this happens my speed goes to nearly 0Mbps, after the file dump it will pick back up to the original speed. The best way I can describe it is the graph which has the download speed looks like a saw tooth. I have tried different ram modules and a "new" ssd, however, it doesn't seem to help cure the issue.If there's any other data I can provide to help diagnose the issue please let me know, diagnostics are attached.Thanks,Dallas unraid-diagnostics-20251215-1640.zip

Reached out to Unraid support and they suggested a disk share as opposed to user share.

But you should at least download to a folder under /mnt/cache instead of possibly creating multiple folders under /mnt/cache since you could end up with lots of user shares sinceOn 12/16/2025 at 9:38 PM, trurl said:Any folder at the top level of that path is automatically a user share.
