TS-1635AX getting slow transfer speeds with Dual 10GB Fiber?

[bobross]

I have a TS-1635AX with both 10G fiber plugged directly into my Windows 10 x64 via Server Adapter X520-2. When I transfer large files over a single 10G connection I get speeds that are basically what you would expect from a 1Gb connection - about 140MB/S. How is this possible when its connected directly? I'm not going through any switch?

If I port trunk on the NAS side and Bridge to connections on the Windows side (verify they both say 20GB) the speed does not get any better. What am I doing wrong here?

I ready that Win10 Pro can't do netwrok teaming? Could I "trick" my system with a VM using Windows server?

Thank you for any suggestions.

...about 140MB/S. How is this possible when its connected directly?

Because the network connection isn't the performance bottleneck. With 10 GbE it very rarely is. CPU or the storage itself are more likely.

What am I doing wrong here?

Not identifying the bottleneck before trying to solve the issue with increased networking bandwidth. When a car at full throttle doesn't do more than 140 km/h, it won't go any faster because you put brand new tyres on the car or make the road twice as wide.

iPerf3 is a good utility for testing link speed between two devices.
It will let you know if your LAN interface is working at full speed.

Test internal read speeds and compare
"qcli_storage -T" -> disk/raid performance test
Using DAC cable or optical?
I suspect those onboard SFP+ connection drivers.

I would search Bob Zelin posts as I believe he has deployed some 1635s and said he couldn’t get full 10GB throughput out of them.

Not sure if he has tested the newer version or not. That being said if you are only getting 100MB ish throughput that seems low.

Also ensure that you have jumbo frames enabled all through the nw chain.

First step as was indicated above is measuring storage throughput inside the box.

No, the opposite, turn off jumbo frames and check it works first.
Jumbo frame mismatch big source of performance issues.

here is the quick miserable answer -
why is this not working ? Why are you getting such horrible speeds ? Because the TS-1635 and the TS-1635ax are a piece of junk. They look just like the TS-1685 and the TS-1677X, but they are not.
They are slow dogs. The 10G ports do not produce 10G speeds. There are more QNAP products like the TS-831X and TS-832X that are in that same category of junk useless products. I have no idea of why
QNAP ever bothered to put 10G ports on these. There is nothing you can to do fix this.

See - now all of a sudden, that extra $1500 for the TS-1685 doesn't seem that expensive ? Right ? QNAP makes some great amazing products. And they make some junk. Unfortunately you purchased junk.
The last TS-1635ax I installed was purchased just as a backup system for a TS-1685. I still regret making the recommendation, when the client said "isn't there anything cheaper that we can purchase instead
of another TS-1685?". Sometimes you have to be burned to learn your lessons.

If you bought the TS-1685 or TS-1667X, you would be getting 1000 MB/sec to your Win 10 PC Intel X520 right now.

Yes I had a client with the same issues and the box was swopped
Did you ever resolve the speed with other 10GbE card fitted, SFP+ or RJ45?

[Bob Zelin]

I have unfortunately installed multiple TS-1635's and multiple TS-1635ax systems. And I have unfortunately installed multiple TS-831X and TS-832X systems. And I have unfortunately installed multiple QM2 cards with Tehuti 10G chips on them.

What can I say. I know fully well that QNAP needs to compete in the low end market with Synology and Netgear, because if this was sales and accounting data, no one would really care. And these boxes may the the correct solution for these applications. But my applications (professional video editing and graphics) require great bandwidth, and these inferior boxes simply cannot perform like their superior counter parts -
specifically -
a TS-832X is not a TVS-872XT. They are both 8 bay QNAP's with 10G ports. It's like another company built the other product.
A TS-1635ax is not a TS-1685. They are both 12 bay QNAP's with dual 10G ports. It's like another company built the other product.

I am not picking on QNAP here - both Synology and Netgear make "good stuff" and they make "crap". I guess it's not "crap" if you are doing accounting data, and are backing up 500 gigs of data.
In my world - 500 Gigs of data is about 10 minutes of media.

If your professional job was to fix Grandma's Windows XP computer - you might do the same junky work, because you just could not be bothered.
