i just upgraded from a slow as fuck Raspberry 3 OMV build to an Odroid XU4 build. After i have configured almost everything i want to, i found out that my transfer speeds with samba are ridiculously slow. At first i thought it was a samba problem but i now think it has something to do with the ethernet. I couldn't really make out any other thread with the same issue. When i copy files between 2 USB 3.0 devices via ssh speeds are ~ 80MB/s, but when i try to copy files from my desktop pc to the OMV system via smb speeds are ~ 10MB/s. When i copy a file from the Odroid to my desktop the speed goes down to ~ 6MB/s. Even though the Odroid has gigabit ethernet i feel like the speeds are more what i would expect with 100mbit/s ethernet. I have to note that the odroid is connected via dlan, which on paper should be able to handle 1200mbit/s. I know that the actual rates are a little slower, but in no way they should be as slow as 100mbit/s. At the moment my issue is, that i don't really know how to progress with my troubleshooting.
Has anybody with a similar setup experienced the same issue? Does anybody have any advice on what to do next?
