JM已经发布到每夜版，内附我的老旧笔记本测试成绩及chrome对比

刚刚更新了每夜版，发现jit已经有4个选项了。。

笔记本是6年前的thinkpad t43，cpu PM1.86G。总的来说，有了20%左右的提高，甚至超过了chrome。。不过这个应该是我电脑的特例，从成绩上也可以看出chrome的测试结果比较不稳定，应该是由于chrome对cpu要求比较高造成的

进步明显啊

chrome其实挺快，但是那个飚CPU飚的心颤，估计什么时候我用 爱妻 了再用，是普通的nightly?有没有界面很卡的说？前几天的nightly受不鸟

加了两个jit，默认为
javascript.options.methodjit.content;true
javascript.options.methodjit.chrome;false

今天的真给力，页面秒开的感觉越来越强烈。

不过覆盖升级后启动减速好多啊……之前大概冷10秒，热3秒。现在冷热都是22秒。

速度是快，但是在我这里打开大多数网页会崩溃(新建的个人配置)。只好继续用老版本，等稳定了再换好了

看着眼馋的很，等b6上来裸奔也要升了，不等扩展了。

确实有很大的进步，不过flash渲染还是有BUG！
