Performance on latest FW 1.0.2.86

[Jayo1177]

"Hi Netduma team,

 

Just wanted to inquire for some insight. I've recently needed to revert to the prior firmware version 1.0.2.82 from 1.0.2.86. It was depressing my performance significantly. I've made the same configuration on the prior fw. I get 1gbps and on the latest firmware I was getting depressed to 500mbps.

Upon reversion, I am not getting fully what ISP router provides. 932-950mbps on ISP router via ethernet & maximally 820 via XR1000. I wonder if there's a particular advise you might be able provide? I'm happy to advise on any settings I have currently. With the understanding from the router speed analyster over 800 will present innacurately but shouldn't a speedtest be unaffected by this?
 

Is depressed performance a known issuue on 1.0.2.86? Is there more fw updates expected? I feel like whatever vulnerability patch quoted in the latest fw could be depressing performance?"

 

I commented this on another post but figured it might be better to create a new post. I've since upgraded back to .86 & performed a factory rest. I figured maybe it would be best to be on the latest FW for support

Hi again, 

I just wanted to offer some additonal evidence for my issue:

Here's a speedtest from speed.cloudflare:

Since the factory rest & viewing other articles on the forum I've since set nat filtering to open & configured my DNS (1.1.1.1 & 1.0.0.1) so here's some screenshots from DumaOS:

I have QoS disabled for now so nothing extraneous would be limiting performance, I guess. Appreciate guidance on this matter. I've seen naterings of a beta firmware. I wonder if this would assist my issues without having to roll back.

You'll note that here I have improved overall speed at 633 but RTT latencies don't seem ideal & it's still depressed in comparison to 1.0.2.82.

The only differences between the two are security fixes so there should not be any difference to how the versions perform, they're usually quite small so I'd be very surprised if it is the cause of the issue. The DumaOS version hasn't been touched between versions either. I don't think there will be any more updates planned unfortunately. Has QoS been fully disabled where it actually prevents you changing options on the QoS page?

The DumaOS version from the beta is the one that's in the public updates now so you're all good on that front. 

What is the model of the modem/router the XR is connected to and how have you set that to ensure all traffic flows to the XR? E.g XR in its DMZ, modem/bridge mode

Are ALL devices connected to the XR or do you still have some connected to the ISP router?

Heya Fraser, 

Appreciate the response. That's fair. Although I can only speak to my experience & I have noted tangible differences in the firmwares. I've had a mission where I suspected it was ISP though the engineer that came to my home did the line test through the XR1000 & from their Virgin Media Hub 5. Full throughput on the router & as I mentioned half that rate from XR1000 lan port (when I opened the NAT type things did improve but it's depressed in comparison to prior firmware with secured NAT. There isn't a lot of flexibility the ISP's router fimware.

I'll apologise I'm not to familar with DMZ settings or where I might get relevant addresses and figures for them. However, ISP router is in modem mode. Previously I did have my Nvidia Shield on the ISPs router & since reconnected it to the XR when I noticed it. It hadn't changed anything that I've noticed

Also I did have QoS set to never & any Congestion Control distributions reset for this troubleshooting.

So for the Virgin hub they may have made improvements but in the past I've found modem mode to be a bit finicky. I'd suggest taking it out of modem mode then it will give the XR an IP address that you can find on the V Hub in the devices section or the same IP will show on the XR System Information page as the WAN IP in the Status box. Then put that IP in the DMZ option on the V Hub - it may be in security settings.

Disable QoS in the Congestion Control menu  fully and then re-test the speed.

[Jayo1177]

Thanks for the guidance on this one. Done as specified. I got it out of modem mode & was able to add the XR to the DMZ at 192.168.0.126.

 

Results present similarly to when the ISP router was in modem mode. QoS fully disabled:


It's a mystery to me. I'd be happy with the older firmware version but it seemed a bit less stable in other ways though speeds were better, running that in the configuration you just advised. For sure I'm happy for any other suggestions should they exist.

You need to click the  icon top left of the Congestion Control panel and there is an option that disables QoS fully
