To help with that effort, we've gathered for your consideration a few of our favorite free Google Chrome. Experience the power enhancements they provide, and in a few days you'll wonder how you ever survived online with a bare-bones browser.
FastestChrome: 正如它的名字让你有所期待一样，安装上它可以为你节省大量的时间。它主要提供一些界面上的操作。比如你选中一个词想知道它的意思时，它会弹出一个浮动框，提供维基百科、Google、Surf Canyon、DuckDuckGo四个搜索引擎来查看这个词语的解释。!(http://images.techhive.com/images/article/2013/02/fastestchrome2-100025495-large.png)
Google Quick Scroll: 这个扩展可以让你直接看到目标网站上的搜索关键词。使用它，每次你点击一个搜索链接，一个包含搜索关键词的小组件会显示在目标网页的右下角，点击组件可以直达你要搜索的关键词位置。
Chrome Toolbox: 这个扩展可以让你一次点击打开多个书签；缓存未提交的表单数据从而避免下次再次输入；在浏览器内部放大图片、视频等等，总之，它让Chrome的用途翻倍了。
运行Chrome，在地址栏键入chrome://flags/ _，回车，打开Chrome实验特性列表，它们会直接影响到你的web浏览性能。如果你想查看其他隐藏的Chrome菜单，在地址栏键入chrome://chrome-urls/_ ，回车。flags页面包含了所有的实验特性，所以我们先来说它。
At this is the point, we'd normally offer a disclaimer about messing around with experimental features in an application—but Google has handled that task quite well on its own. 当你进入Chrome flags页面首先会有如下的警告信息：
Though the stuff we'll discuss doing in this article is more likely to cause simple rendering errors or to adversely affect performance than to wreak any major havoc, caution is appropriate.
Google Chrome's flags menu presents a long list of experimental options, only a few of which focus on performance. They include the following seven options.
Override software rendering list Mac, Windows, Linux, Chrome OS: This option overrides Chrome's built-in software rendering list and permits GPU acceleration on unsupported system configurations. If you're running experimental GPU drivers, switching this flag on will probably shorten loading times for games and videos.
GPU compositing on all pages Mac, Windows, Linux: This option will force GPU-accelerated compositing on all webpages, not just those with GPU-accelerated layers. Enabling this option will probably give you a minor speed boost across the board.
Threaded compositing Mac, Windows, Linux, Chrome OS: Threaded compositing will launch a secondary thread on multicore systems dedicated to webpage compositing. Enabling this option may result in smoother scrolling, even if the main thread is busy with other processing duties.
Disable accelerated 2D canvas Mac, Windows, Linux, Chrome OS: Disabling this option prevents the GPU from performing 2D canvas rendering and causes it instead to use the hot CPU for software rendering.
Disable accelerated CSS animations Mac, Windows, Linux, Chrome OS: When threaded compositing is active, accelerated CSS animations run on the compositing thread. However, running accelerated CSS animations, even without the compositor thread, may yield performance gains.
GPU Accelerated SVG Filters Mac, Windows, Linux, Chrome OS: This option taps your GPU to accelerate the rendering of scalable vector graphics filters, which could speed up the loading process on websites that use a lot of heavy drop shadows or other visual filter effects.
Disable GPU VSync Mac, Windows, Linux, and Chrome OS: If you’re a gamer, you’ve probably heard of vertical sync, aka Vsync. Shutting off Vsync disables synchronization with your monitor’s vertical refresh rate. If your monitor has a refresh rate of 60Hz, for example, disabling Vsync allows the GPU to output at a rate faster than 60Hz—or 60 frames per second—when possible.
Depending on your system's configuration and on your version of Chrome, some of these options may or may not be enabled by default. And depending on the graphics drivers and OS updates you've installed, some of them may not have any effect on performance at all. Nevertheless, it's worth experimenting with them and visiting your favorite websites to see if they produce any benefits. In our experience, the Accelerated 2D canvas and GPU compositing options offer the most extensive advantages. On the other hand, disabling Vsync seemed to cause rendering issues on our Windows 8 Pro-based test systems on websites that use HTML5 animations.
Establishing the benefits (or drawbacks) of many of the experimental settings mentioned above proved to be rather difficult. We did, however, observe some performance differences when we ran quick tests using Rightware's BrowserMark and some of the browser benchmarks available on the IE 10 Test Drive site.
With all of the hardware acceleration options disabled in Chrome, our Core i3-powered Acer TravelMate test system (with 8GB of RAM and Windows 8 Pro) using Chrome v22.0.1229.96 scored 314,359 in BrowserMark, and it managed a frame rate of 16 frames per second in the "Bubbles" benchmark on the IE 10 Testdrive site.
Enabling GPU and threaded compositing in Chrome resulted produced a BrowserMark score of 351,492, but had no impact on the Bubbles benchmark. Enabling the other features (and disabling Vsync) yielded a Browsermark score of 361,687; however, the Bubble benchmark wouldn't render properly and wasn't fully visible on-screen. Reenabling Vsync fixed the Bubble benchmark, and bumped the measured frame rate to 27 fps. Specifically, the Accelerated 2D canvas setting boosted the graphics performance in the Bubbles test.
If you already have a fast system and you keep your software, drivers, and browser version up-to-date, it probably already uses some form of hardware acceleration—and its performance should be quite good. Even so, experimenting with some of the hidden features in Chrome may net some additional performance for free, and that's never a bad thing.
