Mozilla昨日发布了Firefox 4 Beta 7，正式采用了全新的JavaScript引擎JägerMonkey。根据官方测试，在Kraken和Sunspider两个JavaScript基准测试中，Firefox 4.0 Beta 7比当前的稳定版本Firefox 3.6.12快3倍；在V8基准测试中，新版比当前稳定版本快5倍。

Mozilla对比了Firefox 4.0 Beta 7与当前的稳定版本Firefox 3.6.12，今天我们再来看一下第三方测试机构横向对比Firefox 4.0 Beta 7与其它浏览器。根据Computerworld在Vista平台上进行了JavaScript的测试，Firefox 4.0 Beta 7在JavaScript渲染速度上比Firefox 3.6.12快三倍，这一点与Mozilla的官方测试结果相同。

从整体来看，Firefox 4.0 Beta 7以微弱差距负于Opera 11 Alpha。Chrome 8 Beta与两者的成绩也十分接近，几乎比肩，Safari 5.02和IE9 Beta则被前三者拉开了比较明显的距离。Firefox 4 Beta 7的成绩比IE9 Beta高出25%，比IE8的JavaScript渲染快12倍。

JS测试：Firefox 4最新版比IE9 Beta快25% 得分越低越好
