    I think an undervoltage has to be seen in /var/log/pcp_boot.log, but there is nothing.

    Here is the log:

    To setup piCorePlayer, use the web interface via a browser:
     - http://192.168.178.109
    
    Press [Enter] to access console.
    
    In the background, ntpd is syncing time between piCorePlayer and the internet.
    A large offset between 1970 and now is normal.
    But I see now that at boottime the Pi is accessing the external SSD really long. After the LED blinking stops the Pi has started completely.
    For me it seems that the access to the SSD is really slow. But I see no reason for this.
    The above log is done with an ExFAT filesystem on the SSD and only 700 musicfiles to see if there is a difference between hfs+ and ExFAT. But both are slow.

    I would choose ext4, and it might be a bit faster as it is linux native, But is will not explain the difference you seem to experience.

    you could time some disk copy actions to do a rough examination of disk throughput.

    I measured the speed of the drives at my Mac and they are all nearly the same regardless of the filesystem.
    The problem is that I can not easy write to an ext4 partition on my Mac.

    But I think I found the problem. It is the GPT partition format. I choose an ExFAT filesystem ontop of a MBR partitiontable and now it is fast. If I go back to GPT partitionformat it is slow.

    Is it possible that utils-linux.tgz from the piCorePlayer repository has a problem on a Pi 4 installation?

    GPT is in the kernel. Userspace is not needed to mount a GPT. But pCP needs it so that it can find out information about a GPT disk.


    There are all kinds of possible throughput issues on the pi4. What board firmwares are you using?

    I don't know. I simply put it out of the box and installed piCorePlayer, that's all.

    I'm running a 500GB ssd on my pi4 using a MBR and EXT4 partition, no issues.

    The RPI4 has flashable firmware, which is different from all of the previous boards. Firmware update procedure is here: https://forums.slimdevices.com/showt...l=1#post951108

    This firmware is forked from the RPI github, I only tweak the scripts to work with pCP. The firmware installed with these scripts are the same firmware RPI would automatically install on the board if you were running Raspbian.

    That is what I told, No problems with an MBR partition format, only with GPT partition format.

    Now I have the complete music in an MBR partition format and ExFAT filesystem and it took LMS 30 minutes for approximately 42000 files. If I remember correctly the Pi 3B+ needed nearly 1,5 hours. So this is great!

    I tested again a SSD with GPT partition format and ExFAT filesystem and one with hfs+ filesystem and both took nearly 1 minute to mount and they are really slow when reading something.

    Ok! Thank you for the information. I will flash it this evening when I am back at home.

    Just replace 7.9.2 with 8.0.0 in step 5.
    I tried that yesterday, but I still got 7.9.3 not 8.0.0. Why can this happen?

    You made a mistake :-)

    Post full input & output and we might be wiser.

    :-) Normally I would write the same.

    Today I issued the same commands like yesterday (I used them from the shell-history) and everything works.

    Very strange!
