I have never seen this speed, not even in reading! 
In the weekend I'll try the latest stretch 0.6.15 - 175 with default kernel 4.4.103.
I'll check the network performance using netperf with both windows and linux machine, and the USB3.0 local performance with iozone (but if I'm not mistaken it is over 100MB/s).
I can also make a test with Helios LAN test.
Do you need some particular log or output?
Thanks.
I did the test with the jessie OMV 0.6.19 and jessie OMV 0.5.15, using 3 different PC to read from and write to.
One PC with Windows 7, one notebook with Windows 10 and one PC with Ubuntu 16.04 LTS.
All of them have gigabit ethernet, and are directly connected to the router Netgear DGND3700v2 (gigabit ports).
I tried with 2 different ethernet cables to connect the rock64 to the router. The test was done with 1.5GB file.
The average read speed was less than 50MB/s and the average write speed was less than 40MB/s, and there are no significant difference with all of 3 PC.
So i can exclude problem with the "other" PC, and problem with cables.

I think there is no problem with disk neither with gigabit transfer.
What is the problem? I don't know.
But reading the forum, I'm not the only one having this problem.
