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.

    Is it a permanent cable in the walls? In that case you probably want to check the wall sockets first. The internal connection between socket and cable is rather flimsy and the most likely point of failure. You can get a punch down/ LSA tool for under ten bucks and try to fix it. I also recommend a device for testing the lines. Those start around ten bucks and show you exactly which line is broken.

    For wifi: well, the new standards are a lot faster and external wifi 6/ 802.11.ax adapters start at about 30 bucks by now. Internal ones (e.g. intel AX210) are half that and can typically be replaced in laptops (keep in mind that you need the right antennas, you won’t get good results for 6GHz without an 6GHz antenna). And generally internal antennas aren’t as good as having an adapter with external ones.
