Network speed too slow

Banana Pi SBCs design BPI-M3(A83T/R18)
1

Hi, I have the Banana Pi Pro with Bananian (15:04) and have him in the network involved. It acts as network storage (NFS) and home automation. Since I am now switched to HD and have a receiver with 1Gbit interface, I had the speed of the NFS server before incredibly slow. I can only use 8.4 MB / s. Now I have the times with a PC, connected directly to the BPi, tried over NFS and FTP. The same result. Since I used the speed to SD times earlier, I did not care so far. Now it is too slow. What can it be and where do I have to search?With ethtools I have already found out that the interface on the BPi is generally 1000 Mbit, so fitting. Can I still set the nfs server or have I possibly set the wrong? Please help.

Thanks!

I didn’t find the right solution from the Internet.

You could be suffering from thermal throttling. If the chip gets hot, the clock speed is scaled down to prevent overheating. Do you have a heat sink on your CPU chip?

8.4MB/s bottleneck seems to be from the storage system. Is it attached via USB or SATA?
