> ... guaranteed minimal latencies. You could now shave off another 20-100ms of latency for your FaceTime calls... I already do this. But I cheat - I use a good router (OpenWrt One…

The name "bufferbloat" is falling out of favor. First off, it has a horrible sound... And it doesn't really give an intuitive sense of what's wrong. Referring to "latency" or (my f…

What do you think of PRQL ("prequel")? https://github.com/prql/prql

Interestingly, a significant portion of the recent WWDC presentation talked about decreasing buffering in server-side systems. https://developer.apple.com/videos/play/wwdc2022/1007…

As another poster noted, the Feds funded a lot of the cost of electrification. There is starting to be some action on the internet front. But... Here are the economics for a fiber …

@LinuxBender is on the right track. Bufferbloat can cause this kind of lag. (There may be other causes, but first thing to do is check for bufferbloat.) To do this use: http://dslr…

Your router is holding ("buffering") packets in the hopes that they can be sent soon. Your measurements indicate that the router is "bloated", holding about five seconds (5,000 ms)…

Yes. Check for bufferbloat using http://DSLReports.com/speedtest If you get a grade below "B", then your home router is likely bufferbloated. Then read "What can I do about Bufferb…

Yes, we need to emphasize this point. Netflix (and Youtube and Hulu and all the other big content providers) pay big bucks (millions per month) to get the content from their server…

Latency is a measure of how long it takes a packet to go from your computer to some other computer and back. People usually measure this by a ping test Unloaded latency (when there…

I just saw the National Weather Service offers new API info. I have no idea whether this meets your need: https://forecast-v3.weather.gov/documentation?redirect=legac...

> In either case, neither queue builds up in the home router -- that is exactly the problem, since we can't control the queue size in the modem or ISP! But by traffic shaping to 3.…

Yes, but... A "bottleneck" occurs wherever there is a high speed link going to a lower speed link. In your case, the 100 Mbps Ethernets in your home feed through the router to the …

I'm sorry, but I have to disagree. The laws of physics (of the internet) dictate that the piece of equipment at a bottleneck is responsible for handling bloat/congestion on its own…

And there's good news on the Wi-Fi front as well. Many of the same people who brought us fq_codel/cake have new algorithms for "Making Wi-Fi Fast". Their paper tells how they've re…

Yes, but it can occur on both ends of the bottleneck. Your ISP's equipment has a bottleneck link toward your home, and can have bloated buffers on that side. But if your router doe…

Sure, you could make yourself crazy trying to prioritize all the traffic with varying kinds of flags. Or you could just let an algorithm (SQM - fq_codel or cake) automatically dete…

Not so - Bufferbloat can occur everywhere there's a bottleneck link. Your home router's link to the ISP is likely to be one, and most don't have any mitigation, and suffer from hig…

Yes, Don't Congest. But you can spend your life marking various kinds of traffic (many apps already do mark it, as someone down-thread mentioned), and pray that your router (and re…

I'm surprised that no one has mentioned bufferbloat yet. In most home routers, people can see seconds of delay when there's significant other traffic on the link. (And remember, "o…

@pktgen Thanks for the good note. You've nailed the science behind this and the proper fix. In your note below, you also note that Ubiquiti router firmware has fq_codel/cake. I'd l…
