Beta channels primed

The current developer and beta channel releases of Chrome now come with a version of V8 that uses a new counters-based algorithm to decide which functions to optimise, Google has revealed.
Google claimed a 25 per cent increase in speed with Chrome 19, with the updated version of V8, compared to Chrome 18 on SunSpider performance tests.
Traditionally V8 has stopped once every millisecond to look at the running functions and decide which should be optimised. As the Chromium blog put it: "A single millisecond can be a long time to wait before optimizing!“
