Chromium官方博客透露，最新版的Chrome浏览器采用了新的JavaScript编译方法，因此大大提高了性能。文章称，V8引擎优化JavaScript性能的一种方法是通过将JS编译到原生机器码加快执行脚本。以前Chrome是在主线程编译JavaScript，可能会干扰JavaScript应用程序，导致复杂的应用程序如游戏可能会出现响应停顿和丢帧。在最新的bete版中他们启用了并发编译，将大部分的优化编译阶段卸载到一个后台线程，使得JavaScript应用程序保持响应，同时提升了浏览器性能。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
