Google Web Toolkit 2.0 - now with Speed Tracer

Tonight at a Google Campfire One we released Google Web Toolkit 2.0, aiming to do two main things for developers:
  • Make it easier to build faster apps
  • Speed up the overall development cycle
This is a very exciting release because it's the cumulation of a year and a half working with teams like Google Wave, AdWords, and Orkut (among many others inside and outside of Google) to evolve GWT to meet the needs of today's web applications. There are many features and improvements, but let me call out three which we're especially excited about.

Faster Apps

Introducing: Performance profiling with Speed Tracer
The first thing you'll notice in 2.0 is that we've added a new tool called Speed Tracer. Speed Tracer is a performance profiler for Google Chrome that allows developers to see what's going on in a way which hasn't been possible before. We've worked closely with the Webkit community to add instrumentation in the browser to enable developers to gain deep insights into how code behaves, uncovering problems which have been hidden up till now.

Introducing: Incremental app download with code splitting
Another feature we've added into Google Web Toolkit is developer-guided code splitting. Code splitting allows a developer to split up their application for much, much faster startup times. Imagine if you have a settings page that users go to once a week. Why download that JavaScript when the application starts up? With code splitting, your users download just the JavaScript they need to get started.

Faster Development

Introducing: Declarative UI with UiBinder
UiBinder is a new declarative UI framework in Google Web Toolkit which enables rapid design iteration and a clean separation between presentation layer and application logic.

Dive into the details and more features in GWT 2.0.

  6. I wish the speed tracer for chrome supported the "OWN TIME":
    time spent within a function Excluding nested calls.
    this accurately tells which functions take longer to execute....
