As much as a version number means anything at all, a “major zero” version number means that you can expect breakage. This is not what we want to communicate. Especially, it’s not the mindset that we should have towards our users. Hence Syncthing is now graduating from being in perpetual beta to being actual release software, yet the journey of development continues.
As of December 15th 2018, the HTTP Archive is crawling the full list of desktop origins from the Chrome User Experience (CrUX) Report for the desktop crawls (mobile will be added as of January 1, 2019). The URL list used is the latest available at the time of the crawl (November 2018 in this case).
The Chrome User Experience Report is powered by real user measurement of key user experience metrics across the public web, aggregated from users who have opted-in to syncing their browsing history, have not set up a Sync passphrase, and have usage statistic reporting enabled.
由於有條件限制，可以預期會有偏差，不過以目前 Google Chrome 的市占率來說，應該是有意義的資料。而這份資料跑出來的數據看到 Cloudflare 的影響力遠遠超過其他 CDN 讓人頗意外...
In this article, we will show that the FPGA-based real-time VP9 encoding can deliver at least 25% bitrate savings compared to the highest-quality H.264 encoders deployed in Twitch’s production today.
然後提到 1080p60 至少省了 25% 的頻寬 (這邊應該是相較於 H.264)：
VP9’s Compression Efficiency for Live 1080p60 Encoding: We Can Achieve At Least 25% Bitrate Savings
VP9 is implemented in these web browsers:
Chromium and Google Chrome (usable by default since version 29 from May and August 2013, respectively), Opera (since version 15 from July 2013), Mozilla Firefox (since version 28 from March 2014), Microsoft Edge (as of summer 2016).
