This is incredibly confusing and formatted oddly, so let me get some clarification:
- What protocol are you using to mount the NAS to the Ubuntu machine?
- What did you use to transfer this slow file over the network? The disk transfer rate would be much faster than the network in any case, so 160MB/s may just be the network max.
- Have you tried other files and methods to transfer, like SSH, Rsync…etc? Try those and post the speeds.





















That doesn’t look right. What are the two IP’s of the machines on your network?
Edit: you must be using containers or something. Don’t use bridge networking if you’re unsure of the performance issues there.
