Mozilla software engineer Rob Sayre has announced the release of "Kraken", a new browser benchmark. The developer says that unlike other browser benchmarks, such as SunSpider, V8 and Dromaeo, Kraken focuses on realistic workloads and on forward-looking applications.

Sayre refers to a previous blog post where he looks at Firefox scores from previous benchmark tests and to a further reference by his colleague Nicholas Nethercote about the book “Computer Architecture” written by Hennessy and Patterson. In chapter one of the book, they list five benchmark approaches in order of good to poor, ranging from benchmarks based on real applications to synthetic benchmarks based on code conforming to an artificial profile. Sayre says that with Kraken, Mozilla have taken a step in the right direction in building a benchmark that generates realistic workloads.

Mozilla testing with Kraken 1.0 shows Firefox 4 as currently more than 2.5X faster than Firefox 3.6. Kraken 1.0 is available for downloading from Mozilla's Kraken JavaScript Benchmark web page.
