SunSpider в Firefox (сравнение производительности JavaScript)
Решил провести тестирование скорости работы JavaScript трех версий популярного браузера:
- Firefox 3.6.8
- Firefox 4.0 beta 2
- Minefield 4.0 beta 4 pre (ночная сборка 2010.08.08)
Потратив некоторое время в SunSpider, я получил довольно интересные и близкие к действительности результаты:
Mozilla/5.0 (Windows; U; Windows NT 6.1; ru; rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8

Подводя итоги, становится видна тенденция, что новый браузер Firefox 4 от организации Mozilla будет обрабатывать JavaScript примерно в 1.5-2 раза шустрее, чем нынешний. Выход браузера запланирован на конец 2010 года.
