Sun Sayre had the Mozilla developer Rob recently criticized that the SunSpider benchmark V8, and Mozilla's own development Dromaeo far from the reality of work. "We believe the octopuses used in benchmarks in terms of realistic tasks are better for the browser to expand the performance limits," Sayre said now in his blog

Kraken is to measure things, in the opinion of users today are too slow. The progress in upcoming browser versions can be better assessed. The now useable version of Octopus is a first milestone and to be in the coming weeks, extensive development. The benchmark is open source and can therefore be used by anyone and changed. According to Firefox 4.0 in Sayre cuts benchmark Kraken about 2.5 times better than the previous version, Firefox 3.6. In other benchmarks, but was also a significant increase in JavaScript performance to recognize, however, it was not so much from, as in Mozilla's own benchmark.
