It has matured quickly since then: it’s been adopted by Chrome, <a href="http://my.opera.com/desktopteam/blog/2012/07/06/opera-labs-spdy">Opera</a>, <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=528288">Firefox</a> and <a href="http://blogs.msdn.com/b/ieinternals/archive/2013/09/24/internet-explorer-11-changelist-change-log.aspx">Internet Explorer</a>, dozens of server and middleware vendors, and many large sites. SPDY also became the foundation of the <a href="http://tools.ietf.org/html/draft-ietf-httpbis-http2">HTTP/2 protocol</a> developed by the IETF, and is continuing to serve as an experimental ground for prototyping and testing new features for HTTP/2. <br /> <br /> When we set out on this journey the objective was to make the web faster and we wanted to share our latest results. Of course, as with every aspect of performance, the numbers vary for each site, based on how it is constructed, the number of downloaded assets and dozens of other criteria. That said, we’ve observed significant performance improvements in latency—as measured by time from first request byte to onload event in the browser—across all of Google’s major web applications.<br /> <b id="docs-internal-guid-43844bcd-7714-7112-1598-a8054327da03" style="font-weight: normal;"><br /><span style="background-color: transparent;

It has matured quickly since then: it’s been adopted by Chrome, <a href="http://my.opera.com/desktopteam/blog/2012/07/06/opera-labs-spdy">Opera</a>, <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=528288">Firefox</a> and <a href="http://blogs.msdn.com/b/ieinternals/archive/2013/09/24/internet-explorer-11-changelist-change-log.aspx">Internet Explorer</a>, dozens of server and middleware vendors, and many large sites. SPDY also became the foundation of the <a href="http://tools.ietf.org/html/draft-ietf-httpbis-http2">HTTP/2 protocol</a> developed by the IETF, and is continuing to serve as an experimental ground for prototyping and testing new features for HTTP/2. <br /> <br /> When we set out on this journey the objective was to make the web faster and we wanted to share our latest results. Of course, as with every aspect of performance, the numbers vary for each site, based on how it is constructed, the number of downloaded assets and dozens of other criteria. That said, we’ve observed significant performance improvements in latency—as measured by time from first request byte to onload event in the browser—across all of Google’s major web applications.<br /> <b id="docs-internal-guid-43844bcd-7714-7112-1598-a8054327da03" style="font-weight: normal;"><br /><span style="background-color: transparent;

In the two years since we first <a href="http://blog.chromium.org/2011/10/dart-language-for-structured.html">announced Dart</a>, we’ve been working closely with early adopters to mature the project and grow the community. This release marks Dart's transition to a production-ready option for web developers. <br /> <br /> The Dart SDK 1.0 includes everything you need to write structured web applications: a simple yet powerful programming language, robust tools, and comprehensive core libraries. Together, these pieces can help make your development workflow simpler, faster, and more scalable as your projects grow from a few scripts to full-fledged web applications. <br /> <br /> On the tools side, the SDK includes <a href="https://www.dartlang.org/tools/editor/">Dart Editor</a>, a lightweight but powerful Dart development environment. We wanted to give developers the tools to manage a growing code base, so we added code completion, refactoring, jump to definition, a debugger, hints and warnings, and lots more. Dart also offers an instant edit/refresh cycle with <a href="https://www.dartlang.org/tools/dartium/">Dartium</a>, a custom version of Chromium with the native Dart VM. Outside the browser, the Dart VM can also be used for asynchronous server side computation. <br /> <br /> For deployment, dart2js is a translator that allows your Dart code to run in <a href="https://www.dartlang.org/support/faq.html#what-browsers-supported">modern browsers</a>. The performance of generated JavaScript has improved dramatically since our initial release and is in many cases getting close to that of idiomatic JavaScript. In fact, the dart2js output of the <a href="https://www.dartlang.org/performance/">DeltaBlue benchmark</a> now runs even faster than idiomatic JavaScript. Similarly, dart2js output code size has been reduced substantially. The generated JavaScript for the game <a href="http://dart-lang.github.io/pop-pop-win/">Pop, Pop, Win!</a> is now <a href="http://work.j832.com/2013/10/dart-to-javascript-output-size-what.html">40% smaller</a> than it was a year ago. Performance of the VM continues to improve as well; it’s now between 42% to 130% faster than idiomatic JavaScript running in V8, depending on the benchmark. <br /> <br /> <div style="text-align: center;"> <table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody> <tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEimtHBKz2OVhqQyi5HXMK7m902pMx-LXhyLUaWk7fqoL92p0wLn18qP_MxojW3M3twQp9A1I4MHBdVdII5u1TOFq4uYHDyDzl-JDefSy4ftp-Fd304a1PTscRgPEkOVfDaO1MiZWwTbfvWT/s1600/deltabluebenchmark.png" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" height="220" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEimtHBKz2OVhqQyi5HXMK7m902pMx-LXhyLUaWk7fqoL92p0wLn18qP_MxojW3M3twQp9A1I4MHBdVdII5u1TOFq4uYHDyDzl-JDefSy4ftp-Fd304a1PTscRgPEkOVfDaO1MiZWwTbfvWT/s400/deltabluebenchmark.png" width="484" /></a></td></tr> <tr><td class="tr-caption" style="text-align: center;">DeltaBlue benchmark results</td></tr> </tbody></table> </div> The Dart SDK also features the <a href="http://pub.dartlang.org/">Pub</a> package manager, with more than 500 packages from the community.

In modern JavaScript engines like V8, latency comes from two main sources: compiling JavaScript to machine instructions so it can run faster, and garbage collecting memory that is no longer used. These tasks are computationally intensive and if they run for too long can be visible to users as small hiccups and freezes of JavaScript programs. We've added a modified version of our <a href="https://developers.google.com/octane/benchmark#mandreellatency">Mandreel</a> and <a href="https://developers.google.com/octane/benchmark#splaylatency">Splay</a> benchmarks to measure how well JavaScript engines can minimize these pauses. <br /> <br /> We’ve also added two new performance tests that target important use cases. One new test is based on the <a href="http://www.typescriptlang.org/">Typescript</a> compiler from Microsoft, a heavy and complex JavaScript application. Its execution stresses raw execution speed, code parsing and the memory subsystem. We've also included the <a href="https://github.com/kripken/emscripten/tree/master/tests/zlib">zlib</a> benchmark, an asm.js test from the Mozilla <a href="https://github.com/kripken/emscripten">Emscripten</a> suite. Both new benchmarks help measure an engine’s ability to deal with heavy and complex workloads, which are increasingly common in today's web applications. <br /> <br /> Finally, we fixed three existing benchmarks to help ensure that they measure what they were intended to: <br /> <ul> <li><a href="https://developers.google.com/octane/benchmark#regexp">Regexp</a>: verify that regexp calculations give the correct results.</li> <li><a href="https://developers.google.com/octane/benchmark#gameboyemulator">GameBoy Emulator</a>: code that was supposed to run in strict mode now actually runs in strict mode.</li> <li><a href="https://developers.google.com/octane/benchmark#codeloading">CodeLoad</a>: make sure the code loaded is different on every iteration.</li> </ul> Octane 2.0 represents one more step in our continuing quest to deliver the best possible performance for users.

You can run <a href="http://octane-benchmark.googlecode.com/svn/latest/index.html">Octane 2.0</a> in your browser or read the <a href="http://developers.google.com/octane">documentation</a> for an in-depth look at the new benchmarks. <br /> <br /> Posted by Hannes Payer, Software Engineer and Latency Buster <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </noscript> </div> </div> <div class='share'> <span class='twitter-custom social-wrapper' data-href='http://twitter.com/share?text=Chromium Blog:Announcing Octane 2.0&url=https://blog.chromium.org/2013/11/announcing-octane-20.html&via=ChromiumDev'> <img alt='Share on Twitter' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_twitter_black_24dp.png' width='24'/> </span> <span class='fb-custom social-wrapper' data-href='https://www.facebook.com/sharer.php?u=https://blog.chromium.org/2013/11/announcing-octane-20.html'> <img alt='Share on Facebook' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_facebook_black_24dp.png' width='24'/> </span> </div> <div class='post-footer'> <div class='cmt_iframe_holder' data-href='https://blog.chromium.org/2013/11/announcing-octane-20.html' data-viewtype='FILTERED_POSTMOD'></div> <a href='https://plus.google.com/112374322230920073195' rel='author' style='display:none;'> Google </a> <div class='label-footer'> </div> </div> </div> <div class='post' data-id='4789565009543152609' itemscope='' itemtype='http://schema.org/BlogPosting'> <h2 class='title' itemprop='name'> <a href='https://blog.chromium.org/2013/11/introducing-chromium-powered-android.html' itemprop='url' title='Introducing Chromium-powered Android WebView'> Introducing Chromium-powered Android WebView </a> </h2> <div class='post-header'> <div class='published'> <span class='publishdate' itemprop='datePublished'> Friday, November 1, 2013 </span> </div> </div> <div class='post-body'> <div class='post-content' itemprop='articleBody'> <script type='text/template'> The <a href="http://android.com/kitkat">Android 4.4, KitKat</a> release contains a new WebView implementation built on Chromium open source technology. <br /> <br /> The Chromium WebView is a complete overhaul of the Android <a href="http://developer.android.com/reference/android/webkit/WebView.html">WebView</a> API.
