Hi guys,

 

I recently bought a Rock PI 4 and installed Armbian Buster with kernel 5.4.6. The os is booting fine but I am facing major performance issues when trying to download from the internet. I have also a Raspberry Pi 4 connected to the same switch (via LAN) and when I execute the following command

 

curl -L http://speedtest.belwue.net/1G > /dev/null

 

I am getting download speed of approx 8MB/s on my Raspberry but only 2MB/s on my Rock PI 4. From connection side and rooting there is no difference. While using the same Armbian version on my Rock64 I am getting the same speed as my Raspberry Pi. Is this a known problem with the Rock PI 4 or am I missing something important? I also tried other kernel versions but the problem persists.

 

One thing to mention: I tried the same command with a local webserver (same network, same switch) and there I was able to get download speeds of about 60MB/s, so it seems to not being an issue with the LAN port itself. Any ideas?

 

Thanks!

 

Bye

HI all,

 

the issue was related to one of my network cables. After applying a different one the issue was gone.

 

Thanks to everybody who took the time to think about it!
