To calculate your Internet speed, FAST.com performs a series of downloads from and uploads to Netflix servers and calculates the maximum speed your Internet connection can provide.Sep 21, 2022 · My fix for bufferbloat is capping the entire network speed with Limiters. e.g. 50/15 DSL line, I tell Parent Limiters the bandwidth is 47/13. The 500/50 line is told it's 450/40. Whilst you won't reach 100% of line speed, you're leaving plenty of overhead bandwidth available for when the limiters would start dropping packets to tail back the …The only time you regularly use that speed is during a speed test, particularly one geared towards purposefully causing Bufferbloat in order to measure performance. The other possible cause that actually happens is BitTorrent, but even with BitTorrent, you can set the client to cap itself at a % of your top speeds, for example, 400 / 17 Mbps ...

Measure the Bufferbloat: Use the Waveform Bufferbloat Test to measure the latency under load (this is a good measure of responsiveness).

If latency increased significantly with load, …Nov 10, 2022 · Bufferbloat tests indicate I am actually getting 70.6mbps down and 6.34mbps up Bufferbloat tests say I am getting 88ms unloaded latency, +174ms download active, and +0ms upload active I encounter issues when both connected via WiFi and via Ethernet I did not encounter issues at work when using office WiFi I do ...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.

It looks like your router does not have good SQM (smart queue management). Your router might have options for this on its interface which will help your bufferbloat issue. If it doesn't, you could solve this problem with purchasing a 3rd party router with better Queue Management software and QoS configuration options. Bufferbloat test will try to max out your download/upload and monitor RTT of packets during and before. When you saturate a direction, some packets get dropped because of TCP Congestion (FreeBSD by default uses new-reno). Issue is, what packets are being dropped or delayed.Bufferbloat.
