Dart perf Google releases Dart SDK 1.3, promises 2x performance improvement for asynchronous code

Google explains its results come from measuring request-per-second improvements using three simple HTTP benchmarks: Hello, File, and JSON, which improved 130 percent, 30 percent, and almost 100 percent, respectively. Hello provides a measure for how many basic connections an HTTP server can handle, File simulates the server accessing and serving static content, and the JSON benchmark offers a proxy for performance of REST apps.
