Google opens up new front in browser wars with Chrome
By Ryan Paul | Published: September 01, 2008 - 07:05PM CT
Google has revealed plans today to release an innovative new open source web browser called Chrome that includes some extraordinary and unprecedented features. Google says that its new browser will move the web forward and provide a stronger platform for emerging web standards.
The browser is built on top of Apple's WebKit HTML rendering engine, a lightweight renderer that is known for its clean code base, good performance, and excellent standards-compliance. WebKit's versatility and the ease with which it can be embedded in applications has led to its adoption in numerous contexts, including Google's Android web browser. Alongside WebKit, Google will be using its own JavaScript virtual machine called V8, which was designed for high performance and has some compelling features.
One of the most impressive technical innovations that Google has brought to Chrome is a multiprocess design. Each individual browser tab runs within its own isolated process, much like the way that processes work in an operating system. This will massively increase the robustness of the browser by insulating the application from bugs that cause crashes within individual tabs. The tab will go down, but the rest of the browser will remain unaffected. The multiprocess design also reduces the impact of memory fragmentation by ensuring that the memory used by a tab can be reclaimed completely when the tab is closed.
Another unique advantage of the multiprocess design is that it will allow users to see the distribution of memory between the various tabs and plug-ins used by the browser. Users will be able to use Chrome's built-in process manager to see how much memory is being used by each individual tab so that they can properly identify the real culprit when the browser begins to hog resources. Google has a few other strategies for reducing memory consumption too, like extremely aggressive and heavily-optimized garbage collection.
