That take to load on a 100Mbit, 300Mbit, and 1Gbit connection? Save your Question here, I am going to ask my audience for an intuition - how long should Pages are less than 3MB still), and bad because… oh… rather than answer that Test and reports on the induced latency thereof. It loads a small file, a bigger file, and a 10 Mbyte file over the course of its Measure that while under load, presently. The WebRTC component accurately measures packet loss, but does not attempt to Happening increasingly in an age of CGNAT. Web connections common today messes with the page rendering, and that problem is The likelihood of a good user experience, as one broken object on hundreds of The fewer numbers of flows that a web page opens improves The new Cloudflare test more closely emulates a single user’s experience than (and desirable) bandwidth probing behavior of a single BBR TCP flow, and in partĭue to the test not running long enough, or transferring big enough objects. Than dozens, and one of the few (that I know of), also leveraging WebRTC.Īt the same time, it’s not so much right now a speedtest as a “how is my networkīehaving test”, as its early testers are complaining that it doesn’t find theĪctual “speed!” on their gigabit connection! This is in part, due to the natural I rather like the potential in the new Cloudflare speedtest, that arrived last week, because it’s aĭistributed “web worker” one that actually tests the behavior of a single TCP connection, rather Please reach out to other test designer folks and Tweeted, linkedin’d, emailed, and spammed every measurement email list I know Get together and produce a report of what each new test is actually doing. I’ve reached out to all the new “speedtest” designers in the hope that we could Research” - trying to figure out why the bombers aren’t coming back. Hard about what they are not measuring, essentially doing “operations Red-team attitude towards them all is needed, as well as more folk, thinking Solid explanation of what network pathologies they do and don’t cover. Happening, but most really need third party evaluation, and calibration, and a I have many kvetches about the new “latency under load” (LUL) network testsĭesigned and distributed over the past year. What is this "speed" are you measuring, grasshopper? The new features and flaws of, ookla and cloudflare
