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 favorite) "responsiveness&

Interestingly, a significant portion of the recent WWDC presentation talked about decreasing buffering in server-side systems. https://developer.apple.com/videos/play/wwdc2022/10078/

@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://dslreports.com/speedtest This measures the late

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) worth of data. This gives the sending T

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 Bufferbloat?" at https:/

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 servers to the internet backbone. Their contracts with their ISPs

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 isn't much traffic on your connection through your lin

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 1 Mbps upstream your ISP provides. That's a

by richbhanover 10y ago
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 end. Your ISP's head end/DSLAM/etc

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 reduced bufferbloat as well as increa

by richbhanover 10y ago
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 doesn't handle the uplink well, it'll be bloated

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 determine which flows are sending more than their fair share of

by richbhanover 10y ago
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 high latency. (And various ISP's equipment

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 remote equipment) handles the markings properly. Or just

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, "other traffic" can be ordinary web brow

Regrettably, these folks use the "cream of the crop" technologies, but get the wrong answer. (7mbps/768kbps DSL shows up as ~2mbps/560kbps...)
