DS920+ and Asustor AS-U2.5G2 adapter : works but not at full speed for some client/server... #296

Closed MilesTEG1 closed 3 months ago

MilesTEG1 commented 1 year ago

Description of the problem

I bought an Asustor AS-U2.5G2 adapter (not the same as the first gen AS-U2.5G) to replace a probably defect Cable Matters 2,5G adapter. I plugged it correctly in the USB3-USBC adapter supplied with the AS-U2.5G2 (otherwise the 2,5G adapter is show as 1000M instead of 2500M). I also disable IPv6 on the LAN3 (eth2). image

I launched severals iperf3 tests with this command while the NAS is the server with iperf3 -s :

 # Launched on two differents clients : Asustor AS6704T, Macbook Air M2 with an Asustor `AS-U2.5G` adapter
 iperf3 -c 192.168.2.201 -t 20 && iperf3 -c 192.168.2.201 -t 20 -R

The results are distrubing...

With DS920+ as a server :

  • As a client: my MBA M2 with Asustor AS-U2.5G adapter :
    • MBA M2 --> DS920+ ≈ 1,54 Gbits/sec :warning:
    • DS920+ --> MBA M2 ≈ 2,35 Gbits/sec (with --reverse mode)
  • As a client: Asustor AS6704T on LAN1 (eth0) (or on LAN2 (eth1)) port (2,5G) :
    • AS6704T --> DS920+ ≈ 2,13 Gbits/sec
    • DS920+ --> AS6704T ≈ 820 Mbits/sec :warning: :warning: (with --reverse mode)
  • As a client: iMac M1 with Asustor AS-U2.5G adapter :
    • iMac M1 --> DS920+ ≈ 2,29 Gbits/sec
    • DS920+ --> iMac M1 ≈ 2,35 Gbits/sec (with --reverse mode)

With AS6704T as a server :

  • As a client: my MBA M2 with Asustor AS-U2.5G adapter:
    • MBA M2 --> AS6704T ≈ 1,54 Gbits/sec :warning:
    • AS6704T --> MBA M2 ≈ 2,35 Gbits/sec (with --reverse mode)
  • As a client: Synology DS920+ with AS-U2.5G2 adapter:
    • DS920+ --> AS6704T ≈ 898 Mbits/sec :warning: :warning:
    • AS6704T --> DS920+ ≈ 2,32 Gbits/sec (with --reverse mode)

With MBA M2 (with Asustor AS-U2.5G adapter) as a server :

  • As a client: Asustor AS6704T:
    • AS6704T --> MBA M2 ≈ 2,34 Gbits/sec
    • MBA M2 --> AS6704T ≈ 1,58 Gbits/sec :warning: (with --reverse mode)
  • As a client: Synology DS920+ with AS-U2.5G2 adapter:
    • DS920+ --> MBA M2 ≈ 921 Mbits/sec :warning: :warning:
    • MBA M2 --> DS920+ ≈ 1,94 Gbits/sec :warning: (with --reverse mode)

The results with :warning: emoji are weird because of the other results... I don't understand what's going wrong...

Update previous message with last tests results : the server on my MBA M2. It appears, that it's a bit low in performance. I tested the same adapter with my wife's iMac M1, and there it's better.

bb-qq commented 1 year ago

From the iperf3 output, it appears that there are a lot of TCP retransmissions and congestion control is reducing throughput. (see the Retr column)

The combination of MBA M2 and AS6704T also seems to be causing the slowdown, so you may want to suspect the Ethernet cable or switch.

You may also find the Troubleshooting page useful.

That's what I thought, but I wasn't sure the meanings of the Retr column...

The combination of MBA M2 and AS6704T also seems to be causing the slowdown, so you may want to suspect the Ethernet cable or switch.

I already look into the troubleshooting page :) You say that the problem should be the ethernet cable ? It's a 6a cat, 5m length. I can try another one. The switch seems to be OK, I already try another port. And as the problem doesn't occur between the iMac and the Asustor, I suspect the problem is located on the DS920+. My MBA seems to have only uploads problems. From the iMac, it seems there is no problem.

So, for now, I just had to deal with this problem. Next month, I'll buy another adapter for the iMac, so I could test this new one on the Synology.

PS : I didn't change the MTU values, because I can't set a value greater than 1500 on my mac: image I keep the LAN1 (eth0) plugged in another switch (a gigabit one) for all my critical services (reverse proxy, servers, etc...) I set a static route for the Asustor NAS IP : image

I also tried to remove temporally the 1GB link and the tests have the same results.

bb-qq commented 1 year ago

To isolate the cause, it may help to connect the PC and NAS directly with a shorter cable instead of through a switch.

If the problem is on the NAS side, it may be that burst transfers are causing a temporary memory shortage. In this case, you may get some error output to dｍesg.

I tried another cable, and ran an iperf3 from the mac :

Even on the built-in ethernet port (and connected to another switch), there are some Retries! (this test was conduct while the mac were connected to the 2,5G switch, and the NAS to the 1G switch, the 2 switches are linked of course). I tried both connected to the 1G switch, résultats are the same : much Retries.

If I do the same tests with the Asustor as server, I have much much less Retries, 0-20.

Hello, Here some news !

Fist of all, I bought another adaptor, the Club3D one, a CAC-1420 USB 3.2 Gen1 Type-A to RJ46 2.5Gbps. But sadly, I had the same results... upload from my 920+ was pooly bad... like my previous tests.

After cleaning the NAS from the driver and driver's preferences (see #299 ), I installed it again, from scratch. And, after some reboots, I didn't see any new interface eth2... only my built-in eth0 and eth1... I try to uninstall from DSM, reboot, and reinstall it again... with no positive result. 😞 Still no eth2 interface, even if the driver were well loaded and functional...

So I hit lsusb command to see if there is my adapter... No one were listed... Crap... Before the first cleansing of the driver and preference's files, it was on the list... and worked (ok not very well...), but according to the FAQ, maybe a USB Hub with power should resolve stability and low upload throughput... So I bought a powered usb3 hub, and plug my adaptor on it, and it worked... but after uninstalling/reinstalling the driver, it works no more...

I unplug the adaptor from the USB-HUB, and plug it into the front USB-A connector, restart the driver with my script (see #295 ) and Oh-my ! ETH2 was back !! Yes. So, I did some iperf3 tests between my 920+ and my Asustor and see what I get:

iperf Done.

A nearly perfect score 😄 for both ways : up and down ! ! With no retry !

After this success, I try to activate again my static routes I had set before to ensure all traffic go through eth2 interface : image But this caused all bad retry to occurs again with the poor upload throughput... As soon as I deactivated those statics routes rules, my upload throughput was back to full 2,5G speed.

So, for now I let thoses static routes behind, and seek a way to ensure all traffic goes though eth2 interface, while maintaining my eth0 interface up and running.

I just have to decide what to do with the usb hub : give it back to amazon, or keep it in case of I need to plug another usb thing in the 920+, because the other port is used by my UPS.

So for now, all is working fine !

I am glad to hear that it worked successfully.

Is the problem now that throughput is affected when static routes are configured? I am not sure about the configuration of your network, but what happens when you separate the segments?

I'm not sure I correctly understood your questions here...

If static routes are set, the throughput is affected: low throughput. What do you mean with "separate the segments"?

bb-qq commented 1 year ago

I wrote the previous comment in the hope that by creating an independent subnet for the desired route, it would be possible to communicate over the desired route without explicitly assigning a static route.

Sorry if I'm missing the point.

I would like to close this issue as I have not heard back from you in a long time. If you have any questions, feel free to re-open.
