JaegerMonkey:Firefox JavaScript跑分利器?
https://wiki.mozilla.org/JaegerMonkey
希望Firefox的JavaScript性能比Google Chrome差距小一些。 JaegerMonkey (or JägerMonkey) is inline threading for SpiderMonkey. The goal is to get reliable baseline performance on the order of other JS JIT systems. "Inline threading" really just means a baseline whole-method JIT that doesn't necessarily do many traditional compiler optimizations. Instead, it does dynamic-language-JIT-oriented optimizations like PICs and specialization of constant operands. |

linux下编译了一把,编译出来的版本是3.7a2。
about:config里原来的jit改成了tracejit,新加了两项methodjit,图方便没测sunspider,只试了wd-testnet和v8,成绩下降不少,wd-testnet用时是3.7a4(trunk)的8倍,跑v8的分数只有3.7a4的60~70%。 到mozilla wiki仔细看了看,上面说现在JM只能在shell下运行: Currently we only support shell builds. 也就是说现在的JM只能单纯的跑分,和实用不沾边,看完后兴趣全无,一删了之。 |
