Dart 1.3 dramatically improves server-side performance

With Dart SDK 1.3, we’ve improved performance of async code running in the Dart VM and made substantial improvements to dart:io. This results in some of our experimental HTTP benchmarks now running at more than twice the speed of the previous release. We continuously track these benchmarks on the new Dart I/O performance page.

In the Dart Editor, “Run as JavaScript” now uses pub serve, which serves your web app’s assets and does code transformations using a development server built into pub. This makes your development workflow faster and more streamlined.

For users of AngularDart we have other good news in store: the Dart Editor now has support for Angular code completions and improved Angular analysis and refactoring support. Building web apps using Dart and Angular just got even more productive!

You can download Dart 1.3 from the Download Dart page. If you are running the Dart Editor, you can update by checking "About Dart Editor". Don’t forget to tell us what you build with Dart in our Google+ community!
