    • Urgent

    upgraded from 6.8 to 6.9 stable and noticed high CPU used and slow xfer at ~200MB/s instead of +1GB/s between NVMEs

    its not constant 100% but alternating on different HT

     

    Always same Find command /mnt/cache/appdata taking 100% CPU thread

     

    Never noticed that CPU spike on 6.8 release and havent change anything before and after upgrading

    The 'find' command is almost certainly the Folder Caching (Cachedirs) plugin doing its initial scan since you have just rebooted.

     

    You probably want the appdata share to be excluded as if you have something like Plex installed it can contain millions of files.

    Dynamix Cache Directories plugin is installed but the "Scan user shares (/mnt/user):" is set to No

     

    I reverted to 6.8.3 and CPU activity is back to normal

    You might still want to add appdata to the folders to be ignored as even with User Share scanning disabled the folder will still be found and scanned when the drive contains that folder is scanned.

    ok, I will try to exclude appdata and (re) upgrade again to see if that fix CPU issue
