Hotfix for router firmware coming soon? - CPU issues causing ping instability

[GRAAM]

Hi guys,

Ive been keeping an eye out for the new firmware to address the issue highlighted with high CPU usage. Just wondering if there's a hotfix coming soon?

It seems the high CPU usage is causing quite a lot of instability with my ping, so I'm currently reverting to use ISP modem while awaiting the new firmware..

Here's a few screens of my ping stability with the R3 vs my ISP Modem (Vodafone UK).

R3 Ping (firmware 4.0.23) - connected via Ethernet:

ISP Ping - connected via Ethernet:

In both instances, nothing else was running on my internet, both are taken from my PC at different times - connected via ethernet cable.

Background info on my setup:

• I'm on firmware 4.0.23 - I've been testing this out for the last few weeks.
• My connection type is DHCP.
• I have Steady Ping is disabled / Congestion Control at about 87% on dl / Ad Blocker is disabled.
• I have UPNP enabled in both ISP modem and on the R3.
• ISP modem I've set up the R3 within DMZ and with a static IP

Here's a snapshot of my current CPU usage:

Just to rule it out - the router is on a flat surface and well ventilated - so I don't think it's a cooling issue.

Just while I'm posting, I have a few other minor bugs I thought I'd mention:

• IPv6 doesn't seem to be working (as you'll see in the ping graphs above R3 version has a IPv4 address for Google test), I have IPv6 enabled in both WAN/LAN settings.
• Ethernet internet takes an abnormally long time to connect - about 30-40 secs or so, vs 5-10 secs with ISP Modem.

I've included attached a log in case it helps at all. It would be good to get an ETA on the new firmware please - hoping there'll be a hotfix soon!

Thanks!

What is your broadband speed you get to your property? If its a gig line I would not use qos at all as I don't think qos is working well with high speeds. I can stabilise my line using speedtest set up using 500mb down 100mb up and then setting the sliders to like 60% this reduces the speed alot but definitely get stable line some software like dd wrt is also unable to run qos at high speeds maybe it's a similar issue

Only around 56-60mbps. It's DSL rather than gig line unfortunately - my ping is usually really good though as I live in London (near Greenwich) - 6-7ms on ISP Modem / currently 12-14ms on R3.

I've tried setting CC to 60 and it doesn't really make a difference to ping tbh! I only have gaming as a top priority within smartBoost.

I asked about the CPU fix for the past few weeks. It’s very frustrating that a hot fix has not been released. The CPU usage is too high on this router which indicates that DumaOS 4.0 is highly unoptimized. I’ve observed high CPU usage with only a PS5 console attached via network cable idle with no other devices attached via network cable or WiFi.I’m concerned that we’re are getting the run around here. Network latency is a key factor for gaming and the CPU usage on this router is a huge problem. I have over 40 devices attached to my Asus router with concurrent video streaming etc and cpu usage hovers around 10%. It goes up to 35-40% for heavy downloads. With the R3 certain CPU’s spike to 100% at idle. With an average of like 20% usage at all times. This is with just 1 device attached. A PS5 sitting on the Home Screen.

@GRAAMif IPv6 worked then you would have issues with bufferbloat (congestion control not working). I have to disable IPv6 on the Lan and Wan for congestion control to work properly. Congestion control on the R3 with IPv6 fully enabled properly doesn’t work. Known issue. This problem also impacted other Netduma routers. Seems to have made its way into Duma OS 4.0.

I've also noticed traffic shaping gigabit connections are a hassle, its best to leave shaping off and just prioritize gaming traffic only

@swippursorry, not understanding what you’re saying. Are you saying to disable congestion control all together and just gaming traffic?

Yeah as @l2eactionz stated using congestion control at gigabit speeds is pretty CPU intensive. It’s best to turn off congestion control if you have symmetrical gigabit fiber.

Whats odd to me is my fourth core sees next to no activity while core 0-3 are hovering around 80+ percent usage for me.

Same here. This was a more extreme case to be fair, usually its just the one core at 95% usage or so while 2 other stay around the 40 - 50% range and of course the one core not being utilized at all, but every once in a while this happens.

That’s what I’m experiencing with single ps5 attached to the router idle. No gaming or downloads. I’m wondering if the router is overheating. I experience weird issues like ping stabilizer stabilized for 15 seconds then it transitions back to sbalizing.

I believe it is the CPU issue you're experiencing, the firmware is due this week and not only will the CPU usage be drastically reduced, the higher ping/jitter caused by it should be resolved as well. As lot of fixes/improvements in this one I believe.

[cljackhammer]

@Netduma FraserAppreciate the update and professionalism facing customers that might be a little upset.

Novità per l’aggiornamento??

Where do I find this cpu mem usage in dumaos?
