I have rock64 single board computer with openmediavault
I use hdd (Ext4) connected to usb3 port (also i try to use usb3 flash memory)
I share hdd folder through afp smb ftp protocols. Transfer speed is very slow about 10mb/s
I use mac with Blackmagic Disk Speed Test with afp also i try windows computer with smb but i have same result
How i can find bottle neck?
