This is my first time setting up a Raspberry Pi4 (8GB). Before, I have used a RPi 3B for some other things. From what i have read is, that IO performance should be a lot better on the RPi4, as with the RPi3B. But i get the same speeds as before. I have setup the following:

  • Installed Raspbian Lite (64bit)
  • enabled SFTP/SSH
  • Setup a user for SFTP only access, with home on a connected USB HDD
  • the USB HDD is connected to one of the USB3 ports
  • This is the same setup on the RPi3B

When I now try to start to copy a 2GB file from my Laptop via LAN, i get in both cases a max of 11.6 or 11,5MB/s. But according to articles like this (https://www.jeffgeerling.com/blog/2021/raspberry-pi-25-gbps-16-tb-omv-nas-setup-and-performance), it should be much faster. Is there some secret, or whats the problem?

BTW: The Laptop runs on Manjaro Linux, where i start the transfer, there is no Windows available.

    Alles gut :-) Das Problem ist gelöst. Die Dachdecker haben das LAN Kabel beschädigt. Werd mal ein Neues am Montag ordern. Ich hasse es nur, das Kabel zu verlegen. Das liegt teilweise unter dem Laminat im Flur, was ich mühsam verlegt habe. Was solls, da muss ich wohl durch.
