Ready NAS 102, What is the maximum throughput possible with this NAS?
I know this subject has been discussed before, but I haven't found a posting that really answers the question. I realize there are many, many factors that affect what one actually achieves but I woul...

I've used iPerf3 to test the network from the ReadyNAS, it achieved near full network speed, 900 Mb/s. I logged in as the root user and per the top app the iPerf3 process was using 97% CPU. I copied a 2 GB folder to another folder on the NAS and the copy rate was 55 MB/s (444Mb/s) using 45% CPU. I then used Windows to copy the same 2 GB folder to the NAS. The transfer rate was the measly 15 MB/s with the smbd process using 90% of the CPU. Logging on as root on my Synology NAS, scp to and from this nas was only 12 MB/s.
Any ideas where I go from here? Are there other Debian tools I can use to figure out what's happening?
Have you tried using a single 2 GB file to test instead of a folder? I suspect that will give different results.

I have verified that a 1 GB file has the same transfer rate as the folder I'm using. I hear what you are suggesting.The folder I'm using has 20 100 MB files. I constructed these folders specifically to test transfer rates. I also have folders with smaller files to test how the systems deal with a large number of small files.
I have used the same test files when testing the between my PC and the Synology NAS which is able to achieve 980 Gb/s for both read and write.
I have also copied the folder and the file. between the Synology NAS and the ReadyNAS. The throughput is limited by the ReadyNAS.
