I'm only getting half speed when downloading from my new Unraid 6.11.5 Server. Uploading to it gets the full Gbit, but downloading doesn't.
This is my first time using Unraid, so I'm not sure where to look.
I found the other topics talking about realtek nics, but I have a Intel NIC. Tried a different Port on my Switch and a different Cable. Other PCs on my network get full speeds in both directions between each other, but always only half downloading from Unraid.
Tested with iperf3 and openspeedtest running in Docker on the server.
