Fixing Network Latency and Reducing Bufferbloat (WANT MORE WINS!?)

[@capplanetfresh3687]

This is truly awesome content. Thank you! And I got some quick questions for you, if you don’t mind. Okay so, what are the best routers to flash, say top 3? Also would you say you need a desktop computer to get these type of optimal results? Lastly, can you post some videos in depth on how you flash your hardware? Thanks again

[@capplanetfresh3687]

The reason I asked if I needed a desktop is because I’m a console gamer 🎮 however, I want those great results. Or at least close to it

[@Davefinito]

Thank you so much! To flash OpenWRT, the Linksys WRT3200ACM works really well. I actually bought it to flash OpenWRT as it was compatible. As for others, I know other routers have the capability but done don’t. I use the OpenWRT forum and look at the routers to make a decision. Some routers aren’t compatible and could get bricked. I posted a video how to turn a pc into an OpenWRT router. Just need 2 gigabit ports that are compatible. Results I shared were on desktop but would be the same with console. It’s how the traffic is handled and prioritized on the router to minimize jitter.

[@capplanetfresh3687]

TheDaveStuff Of course, I’m just giving credit where credit is due! But okay I see, I’m probably gonna invest into the WRT. I’m just gonna make sure I can get the router properly Flashed first. If I can get that under control, then everything should be good. But thank you for the very useful information

[@Davefinito]

Would you rather lower your broadband speed in exchange for lower network lag or would you prefer more download and upload?

[@smwfreak1647]

for some programs i would lower how much speed it gets to use but to be honest in general i rather more download and upload speeds :)

[@Davefinito]

I think there’s a major opportunity missed by the network router companies. Using old algorithms doesn’t help today. I can say for gaming but it also applies to any app or service. I’d be willing to have a bit of telemetry on my router IF they intend to make a substantial change. Maybe even pay $2.99/ month if they can really make it amazing. I value my time and will pay a cup of coffee a month. 🙂 People focus on input lag reduction on their PC. But for online stuff, the routers need to be better optimized. If routers can’t manage traffic properly, forget any sort of input lag adjustments or tweaks. Milliseconds today make a difference.

[@Raglarak]

@@Davefinito Nice video, do you have another video with the best ethernet settings for gaming, as well as best tcp flow control provider etc. ?

[@davetaht4989]

Thx for the vid. Retransmits are actually due to "enough" packet loss to hold the latencies down. To avoid retransmits, turn on ecn on your clients and servers.

[@Davefinito]

Thanks a lot for the additional info!

Bought a eero mesh router as it has SQM built in using the labs beta feature set. Now all buffer bloat is gone and I can get decent ping even when other people are watching Netflix etc. It's excellent.

[@sokeeth]

I will try that hopefully it works the same for me aswell

[@djhixson88]

I'd do this in a heartbeat if my router was compatible (Nighthawk X8)

[@mariiisek]

For me SQM didnt fix a single thing, yes on bufferbloat tests it show low latencies, but ingame i still have poor hitreg and feel delayed. I think SQM cant solve it if it is ISP problem right?

[@iDrkTV]

On Xfinity's speed test website, I get 940+ mbps download speeds.. But on this dslreports speed test page, I only get 480-500mpbs? What's the difference? And I got an 'A' under blufferbloat. Is that generally good enough? Or do I need to go through all of this craziness to try to lower it to an A+?

[@jerry84884]

I have a question. Since I have a cable connection and I only have a cable modem that doesnt support sqm and I have EXTREME buffer bloating with it. Can I fix the bufferbloating by installing a router that supports sqm between my computer and the cable modem?

[@X_B0LT]

hi,nice video my question is what version i can install to my old tp link 1043ND v1 i need use how bridge mod i actually have installed DD WRT but i feel i have bad config my bufferbload is supper high maybe cuz im an new in the theme.

[@Chris-qc3uy]

So what I am hearing, packet retransmission is the key? Any good testers for packet retransmission besides dsl reports?

[@roderickmims4802]

can you do a setup for open wrt, I experience low bandwidth with OpenWRT.

[@Davefinito]

I used high bandwidth in my example but works with low bandwidth. I reached the cap limit. For lower bandwidth, same rules apply. Start with advertised ISP speeds and bring it down until bufferbloat is minimal or non existent

Dslreport doesn’t work for me. Says server not available maybe cuz I’m from Europe

[@OkiniriAim]

Hello, thank you for your videos. I have problem: I setting my PC how you advice, but in LatencyMon i have Highest Interrupt about 50-100. My PC: I7-3770, 16 Gb RAM, GTX 1060 3 Gb, SSD 256 gb. P.S. Sorry for my bad english.

[@Davefinito]

Hey. 50-100 may be fine depending on what’s running. Do you happen to know what app is the highest? If your power plan is set to balanced, you can change it to high performance. The second tab in Latency mon can give more specifics on running processes and averages. That might help you isolate what the app or service could be.

[@OkiniriAim]

@@Davefinito Thanks for answer. Highest app is nvddmkm.exe, dxgkrnl.sys, ntoskrnl.exe (I don't know how it disable). Power Plan is High Performance with Quick CPU. I remember you have same problem on twitch one week ago.

[@Davefinito]

Yeah, I had an issue last week with nvlddmkm.sys. Part of it was caused by ntoskrnl.exe. To address the issue, I disabled C-states and set the idle load to typical. The trade off was increase the average DPC from 0.98 to 1.4 microseconds. But it brought down both nvlddmkm.sys execution times from .8-1.3 milliseconds down to 0.018-0.05 average. So power savings was the cause. You may want to look into that. The only Cstate that ideally should be on is C0. Other things to look at are in power settings is to disable USB3 suspend timers. You can also disable power management / power savings of your USB and network card devices from device manager.

[@OkiniriAim]

​@@Davefinito I'm sorry if I disturb you. I disable C-states in BIOS and power management in device manager and results every time different: in Frirst time: 20, in second and third: about 120, in fourth time again 20. Highest app nvlddmkm.sys and ndis.sys.

[@Davefinito]

From time to time these drivers maybe use a little more execution time. If you check the second tab, it’ll display the average and highest execution times. If it doesn’t happen much, not a big deal. The important thing to realize here is after you make a change try it in the app or game. Don’t get too hung up over a metric. It’s 0.02-0.12 milliseconds (20 micro seconds to 120 micro seconds). Reaction times are easier to adjust in comparison.

[@AI-EXREYFOX]

so you use sqm no wan and lan, on wan download is "ingress" and uploud is "egress" and on lan is the inverted right???

[@AI-EXREYFOX]

Dave you have fiber from a ONT, do you have to config PPPoE or vlans to have internet.

[@Davefinito]

No, I have dynamic IP. 3 VLANs are used. 1 for the ISP to manage their router (if used), 1 for internet, 1 for TV (not used).

[@Davefinito]

If you used OpenWRT to flash it, I can only point you to the OpenWRT site to see if you can recover. openwrt.org/toh/hwdata/tp-link/start Checking that list - Only version 4 is capable of running OpenWRT. Versions 1-3 and 5 and 6 all have warnings stating not recommended. Take a look on the site and review recovery options, and go to the forum and ask if necessary.

[@MikkoRantalainen]

It's truly sad that Windows cannot handle network queue management and avoid bufferbloat by itself. Getting something like EdgeRouter X will fix the problem by purchasing yet another network device running Linux with the only task of implementing sensible queue management. If you have a network full of Linux computers and just set default congestion control algorithm to CDG and use the (default!) fq-codel queue management, you'll find that you don't have bufferbloat even without any central router with active queue management.
