火狐4的JavaScript引擎最佳化工作馬不停蹄的繼續著，
目前已經有許多好東西被加進來了。包括這幾天進入每日版的Yarr！
之後還有更多重點的最佳化要被加入，想必非常值得期待。
雖然沒有Opera工程師的肝，但這段時間Mozilla的工程師們真是做了不少努力...
讓我們由目前arewefastyet.com上面的數據，來看看小猴子們進化的怎樣了XD
Jaegermonkey ┬ SunSpider：699ms(7/22) → 525ms(8/13) 進步24.9%(-147ms)
└ V8 ：6697ms(7/22) → 5106ms(8/13) 進步23.8%(-1591ms)
Tracemonkey ┬ SunSpider：694ms(7/22) → 597ms(8/13) 進步14.0%(-97ms)
└ V8 ：6953ms(7/22) → 6100ms(8/13) 進步12.3%(-853ms)
才短短三個禮拜的時間，小猴子們就已經進步這麼多了！
加上Jaegermonkey(JM)持續最佳化，還有祖傳Tracemonkey(TM)的加持，
超越已經快到接近瓶頸的Webkit瀏覽器的那天，指日可待啊XDD
然後JM+TM也已經進入初步整合的階段，

雖然SunSpider比較怪一點，整合後的版本還是稍慢於JM，但看看V8則是表現頗亮眼的。
而且從現在還沒有做太多最佳化，就可以進步這麼多來看，真是潛力無窮～
最後附上我在我電腦上，用SunSpider 0.9.1做的一個小測試，
由（From）Firefox 3.6.8到（To）今天的Minefield 4.0b4pre(Gecko/20100814)，
稍微來窺探一下未來的火狐效能吧。
