Nie tylko o przeglądarkach...

Wczoraj w trunku WebKitu wylądował SquirrelFish Extreme – udoskonalony silnik JavaScriptu dla silnika WebKit.

Pierwsze testy, które przeprowadziłem wykorzystując do tego benchmark SunSpider z użyciem WebKit r36247 dla Mac OS X oraz Minefield/3.1b1pre Gecko/20080907020345 dla Mac OS X z włączonym silnikiem Tracemonkey wskazują na 40% przewagę tego pierwszego.

Niesamowite... Zastanawiam się, gdzie jest kres możliwości przyspieszenia JavaScriptu?
