I recently bought a NanoPi R5C and installed the Core Debian OS on it. When I used iperf3 to test its up/down speeds, the results are over 200 MB/s. It's not bad. I then successfully installed OVM6 NAS with no problem. When I tested the NAS read and write speeds, I found the speed of reading file from the NAS share was not bad. It was around the speed measured by iperf3, i.e., about 200MB/s. However, the speed of data written to the NAS was very low. It was only about 10 MB/s. What are everybody else's experiece? Is there anything I can do to improve? Please let me know. Thanks in advance!
