Wikipedia defines it as: “Bufferbloat is a cause of high latency in packet-switched networks caused by excess buffering of packets. Bufferbloat can also cause packet delay variation (also known as jitter), as well as reduce the overall network throughput. When a router or switch is configured to use excessively large buffers, even very high ...Currently, the most comprehensive speed test for the measurement of bufferbloat is provided by DSL Reports. You can measure your bufferbloat here: DSL Reports Speed Test. The speed test continually checks latency from the start to the finish of the test, not just at the beginning (like most other speed tests). If the latency rises substantially ...Yes as far as I can see, if you want to limit Bandwidth overall then use Congestion Control - this is the main tool to eliminate lag/bufferbloat. If you want to assign bandwidth as a hard limit you'll need to disable share excess but all devices will then be hard limited to the allocation of the available bandwidth.5. Finally, if none of these seem to be options, call your router vendor’s support line. With the information from the DSLReports Speed Test or the Quick Test for Bufferbloat in hand, you can mention that the ping times get really high when up/downloading files, and that it really hurts your network performance.Pinging from the router, and doing the speedtest from a device connected through Ethernet, I get full speed speedtest (950 Mbps down, 940 Mbps up), and the ping goes to 7ms to 20ms during the test. Latency always increases when you load a circuit. You need to check your hardware stats to see if it is on your end.The result was laughably bad - I went from 100mbps to 20mbps download with a bufferbloat score of "C". I then turned back on adaptive QoS with the same bandwidth limitations. 100mbps download with a bufferbloat score of "A". I wish I could test it without any QoS whatsoever. If I figure that out, I'll let you know.The old DSLreports bufferbloat test used to be the industry standard, but their service has degraded over time (insufficient test nodes) so we’ve discontinued our IQtest that was based on it. We now recommend the Waveform Bufferbloat test. It is generally good but is sensitive to the browser and machine it is run from.
