How to Reduce Network Latency Significantly (Bufferbloat)

[@anceltweaks]

For those wondering how to set bbr2 congestion control provider, I have a file in the resources channel of my discord server that does it for you

[@kylerplayz123.]

the discord link dosent work for me

[@lobotomizedamericans]

Remember the ONLY version of Windows that supports BBR2 are 22H2 and *up.* If you try to enable it on prior versions like 22H1 it won't work, you'll simply receive an error.

[@clingyants]

I don't know how. I did all this as in video, in hopes to reduce my 100ms upload latency. Doing it all, and after restarting PC, my upload ms reduced to 4!!! What the hell? Looks like all this fixed it! Thanks man!

[@anceltweaks]

Glad I could help

[@hudramina]

Bufferbloat is a complex issue that is often misunderstood. The network settings adjustments on a PC suggested in the video might slightly improve performance for certain scenarios, but they do not address the root cause of bufferbloat. Bufferbloat occurs when too much data is queued up in a network device (such as a router), waiting to be sent, leading to high latency and packet loss. This problem often occurs at the narrowest point of connection, where the capacity is the smallest-often between the router and the Internet Service Provider (ISP). To effectively combat bufferbloat, solutions need to be implemented at the router or isp level. One approach is using Smart Queue Management (SQM) techniques, such as FQ-CoDel or Cake, which aim to optimize queue length, thereby reducing latency without significantly impacting throughput performance. These techniques intelligently prioritize traffic and prevent the queue from overflowing, which causes bufferbloat

[@anceltweaks]

They are many ways to deal with bufferbloat and the ways I showed in the video they are two main ones that do affect bufferbloat, being the autotuning level and limiting bandwidth. By disabling autotuning u avoid letting the OS increase the TCP window size largely which can cause excessive buffering. Instead it uses a static window size which would lead to a more consistent less variable network behavior, but a reduction in throughput due to less dynamics which can be seen in test results. As for limiting bandwidth which is done on the router side, you prevent the overflow of network buffers and create a more consistent data flow that the system/router can handle. As for the other things in the video, those are just little things that I added that do not make a significant difference but a little something.

[@hudramina]

@@anceltweaks Imagine our network as a funnel into which water is being poured by one or several devices simultaneously. Your optimization strategies are akin to the effort to individually control the rate at which a single device or multiple devices contribute to the overall flow, in order to prevent the funnel from overflowing. However, no matter how precisely we regulate each device’s contribution, we often encounter the problem of a funnel outlet that is too small-equivalent to the limited capacity of the connection between the router and the ISP in our network. Effectively combating bufferbloat, therefore, requires a comprehensive approach that not only involves fine-tuning on individual devices but also takes the entire network system into account to ensure a smooth and congestion-free data flow.

100% My unloaded latency is 4-5ms on a 500Mbps symmetrical fibre connection but Waveform bufferbloat would often give me an A or B rating. I have the Asus TUF AX-3000 router and have found though lots of testing, that by limiting the Adaptive QoS to a maximum cap of 300Mbps is the only way to completely eliminates Bufferbloat on this router. So far this provides a consistence A+ score with 0ms latency added for both download and upload. I believe the main limitation is due to the router CPU bottleneck which means I will need to upgrade if I wish to benefit from the full bandwidth of my connection.@@hudramina

[@wavyy9425]

ngl out of all the bufferbloat videos i watched this one really helped me. At first i had a A: 5ms +10 +0 now i have A+: 5ms +0 +0 I currently have verizon fios 300mbps up and down and got this wit the default ISP router i thought I wouldve needed a router wit SQM to get a A+ Im happy i came across this video I appreciate the help

[@wavyy9425]

For some reason when I try using OBS I get dropped frames wit TCP Window Auto-Tuning on Disabled but when I put it back to normal It doesn't happen. Im using 8000kbps bitrate and it doesnt drop, it just the dropped frames. I have 1gig which is way more than 8000. How can I fix this

[@biglucagamer90-36]

Hi, thanks to your video I solved a big problem with ease: I solved the bufferbloat from 140 to 8!!! Now I have a good connection! Now a question: is it worth buying a Netuma R3 router!? Or do I just stay with the Fritzbox 7590 and TCP Optimizer? Thanks.

[@Phillydreaming]

very informative video, i tried a game of csgo after doing this and the massive lag spikes were gone but there was more spreadout jitter, but it was definitely more playable. only thing that sucks is on my 1gbps internet the download speed with these settings is like 40mbps. but at least i don't lag in-game anymore.

does all these optimizations works for wi-fi too ? i would like to do them on my laptop.

Being a minecraft player, I've come across the term TCPNoDelay before. What impact does having everything involving Nagle's algorithm at default on other games than Minecraft?

[@anceltweaks]

It just reduces the number of small packets by delaying them, if you’re looking for a low latency system you disable it which disables nagles algorithm

[@strsadigi]

​​@@anceltweakstcpnodelay value DOESNT work on windows 7 and above. you cant disable nagle's algorithm globally in linux and windows 1. in tcpip.sys strings there is not tcpnodelay anymore. 2. it is not synchronized with network shell of windows 3. we can not also see tcpnodelay in windows boot dump but tcpackfrequency and tcpdelacktick is working so you can disable tcp delayed acknowledgement but not nagle's algorithm

[@napom7714]

What do you recommend for geforce now since the program needs good download speed, keep tcp windows auto tunning disabled or normal? When I disable it in the test it gives me an A as a result and when I set it to normal it gives me a C

80/90% of the bufferbloat is on the router and/or your ISP At Windows level you can improve a bunch of ms but nothing to significant because time sensitive data uses UDP and not TCP making TCP optimizers useless. Get a proper router with QOS or SQM. For Gaming NetDuma R3/2 For more control and flexibility EdgeRouter modems... I jumped from 200ms bufferbloat to 1ms using both of those modems The edgerouter is cheaper you can find it for 50$ You can buy a used NetDuma R2 for 80$ Or buy the new R3 for 200ish $ of you are serious about eSports
