Thank you for the update, and especially this very detailed changelog! I'm impressed! A few points on the specific items below: > * We changed the way the speed tests run to show an instantaneous > speed as the test is being run. Much better, I can actually see what's going on now :) Maybe an 'abort' button somewhere would be useful? Once you've clicked start the only way to abort is currently to close the browser tab... > * We moved the bufferbloat grade into the main results box. Also very good! > * We tried really hard to get as close to saturating gigabit > connections as possible. We redesigned completely the way we chunk > files, added a “warming up” period, and spent quite a bit optimizing > our code to minimize CPU usage, as we found that was often the > limiting factor to our speed test results. Yup, this seems to work better now! I can basically saturate my connection now; Chromium seems to be a bit better than Firefox in this respect, but I ended up getting very close on both: Chromium: https://www.waveform.com/tools/bufferbloat?test-id=b14731d3-46d7-49ba-8cc7-3641b495e6c7 Firefox: https://www.waveform.com/tools/bufferbloat?test-id=877f496a-457a-4cc2-8f4c-91e23065c59e (this is with a ~100Mbps base load on a Gbps connection, so at least the Chromium result is pretty much link speed). Interestingly, while my link is not bloated (the above results are without running any shaping, just FQ-CoDel on the physical link), it did manage to knock out the BFD exchange with my upstream BGP peers, causing routes to flap. So it's definitely saturating something! :D > * We changed the shield grades altogether and went through a few > different iterations of how to show the effect of bufferbloat on > connectivity, and ended up with a “table view” to try to show the > effect that bufferbloat specifically is having on the connection > (compared to when the connection is unloaded). I like this, with one caveat: When you have a good score, you end up with a table that has all checkmarks in both the "normally" and "with bufferbloat" columns, which is a bit confusing (makes one think "huh, I can do low-latency gaming with bufferbloat?"). So I think changing the column headings would be good; if I'm interpreting what you're trying to convey, the second column should really say "your connection", right? And maybe "normally" should be "Ideally"? > * We now link from the results table view to the FAQ where the > conditions for each type of connection are explained. This works well. I also like the FAQ in general (the water/oil in the sink analogy is great!). What did you base the router recommendations on? I haven't heard about that Asus gaming router before, does that ship SQM? Also, the first time you mention the open source distributions, OpenWrt is not a link (but it is the second time around). > * We also changed the way we measure latency and now use the faster > of either Google’s CDN or Cloudflare at any given location. Are you sure this is working? Mine seems to pick the Google fonts CDN. The Javascript console outputs 'latency_source_selector.js:26 times (2) [12.81000001472421, 12.80999998562038]', but in the network tab I see two OPTIONS requests to fonts.gstatic.com, so I suspect those two requests both go there? My ICMP ping time to Google is ~11ms, and it's 1.8ms to speed.cloudflare.com, so it seems a bit odd that it would pick the other one... But maybe it's replying faster to HTTP? > We’re also using the WebTiming APIs to get a more accurate latency > number, though this does not work on some mobile browsers (e.g. iOS > Safari) and as a result we show a higher latency on mobile devices. > Since our test is less a test of absolute latency and more a test of > relative latency with and without load, we felt this was workable. That seems reasonable. > * Our jitter is now an average (was previously RMS).

Thank you for this! It even works without allowing all the shopify scripts, so that's all good :) -Toke _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
