![]() With an allocated process in place, the execution of a web program primarily involves three tasks: fetching resources, page layout and rendering, and JavaScript execution. In fact, it is important to note that most other browsers have followed suit, or are in the process of migrating to similar architecture. In an increasingly multi-core world, the ability to isolate the processes as well as shield each open tab from other misbehaving pages alone proves that Chrome has a significant performance edge over the competition. A bug in any page, or the browser, ran the risk of compromising the entire experience.īy contrast, Chrome works on a multi-process model, which provides process and memory isolation, and a tight security sandbox for each tab. All open pages shared the same address space and contended for the same resources. Prior to Google Chrome, all major browsers were built as monolithic, single process applications. The Many Facets of PerformanceĪ modern browser is a platform, just like your operating system, and Google Chrome is designed as such. ![]() Each of these deserves its own dedicated chapter, but since our subject is performance, our focus will be primarily on speed. In turn, the ever more ambitious applications require speed, security, and stability. Simplicity Create sophisticated technology, wrapped in a simple user experienceĪs the team observed, many of the sites we use today are not just web pages, they are applications. Stability Provide a resilient and stable web application platform Security Provide the most secure environment to the user The core principles that motivated the original development of the browser continue to be the guiding principles for ongoing improvements in Chrome: Speed Make the fastest browser The original 38-page comic book explanation of the ideas and innovations of Google Chrome offers a great overview of the thinking and design process behind the popular browser. Clearly, the features and the functionality resonated with the users, and many innovations of Chrome have also found their way into other popular browsers. Today Chrome is one of the most widely used browsers on the web ( 35%+ of the market share according to StatCounter) and is now available on Windows, Linux, OS X, Chrome OS, as well as Android and iOS platforms. "It was so good that it essentially forced me to change my mind…" - Eric Schmidt, on his initial resistance to the idea of developing Google Chrome. To many observers, this turn of events came as a surprise: the return of the browser wars? Could Google really do much better? The Google-authored code powering Chrome was also made available under a permissive BSD license–also known as the Chromium project. ![]() Google Chrome was first released in the second half of 2008, as a beta version for the Windows platform.
