Safari 4.0 beta, dos veces más rápido que Safari 3.1.2 en JavaScript
Publicado el 3 Julio 2008 por juandesant0
Utilizando el test de velocidad de JavaScript SunSpider, creado por el equipo del WebKit, he comparado en la misma máquina el rendimiento de Safari 4.0 (en realidad, utilizando el WebKit r34974, pero los cambios en estas revisiones del WebKit acabarán formando parte de Safari 4). Esto demuestra que, pese a la buena velocidad de Safari 3.1, los cambios que se están haciendo en el nuevo intérprete de JavaScript realmente merecerán la pena cuando Safari 4 salga de la fase beta.
A continuación, el listado de resultados de comparar ambas versiones:
