Poor CIFS Speed
i have the problem, that the transfer speed from and to the Nas is very poor.
At write to the Nas i become approx 60MB/s and at reading from it, it will be approx 65MB/s.
The same, when i config the Drives to a stipe set, or mirror, or Z2. I use a Dell T20 with 16GB ECC Ram and a Xeon 1225v3 CPU, the drives arte two WD Green with 2TB and two Samsung HD204ui with 2TB too.
Former i used as OS MS Server 2012R2 and here ich had approx 95-100 MB/s. So i rekon, the problem lay at the CIFS Service.

So i had testetd my complete network enviroment for any problems, but find no problems.
The transfer speed between my computers are at 95-100MB/s, so i can say, that is no network problem.
I tried on the FreeNas a stripe, a mirror and a Z2 Volume, with and without encryption, but it will be still at all at 60-65 MB/s.
I think, the cpu (Xeon 1225v3) ist strong enough to made the calculations for the raid, and the memory (16 GiB ECC) is more than sufficient.
So i dont now, what the problem is, especially i had fresh setted up the whole system twice, with the same result.

I had attached a Picture, where you can see the network activity and the transfer speed at 5 times.
It is possible the problem are made from the build in network chip from Intel (I217-LM) in the T20?
Under Server 2012R2 the transfer speeds riches approx 90-100 MB/s, so my rekon is, that the drivers implemented into FreeBSD are not perfect fit for that Chip.

OK! So i had solved the problem while i delete and add the network interface new.
So i think the interface had hanged while the setup process.
I had fresh installed twice the FreeNas and every time i had the same problem.
So now i tried a third time and it works fine for me.
Now i have transfer speeds by approx 100-110 MB/s. :-))
You can now close this Case, except you have further questions.
