Book High Performance Web Sites

Download or read book High Performance Web Sites written by Steve Souders and published by "O'Reilly Media, Inc.". This book was released on 2007-09-11 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Want your web site to display more quickly? This book presents 14 specific rules that will cut 25% to 50% off response time when users request a page. Author Steve Souders, in his job as Chief Performance Yahoo!, collected these best practices while optimizing some of the most-visited pages on the Web. Even sites that had already been highly optimized, such as Yahoo! Search and the Yahoo! Front Page, were able to benefit from these surprisingly simple performance guidelines. The rules in High Performance Web Sites explain how you can optimize the performance of the Ajax, CSS, JavaScript, Flash, and images that you've already built into your site -- adjustments that are critical for any rich web application. Other sources of information pay a lot of attention to tuning web servers, databases, and hardware, but the bulk of display time is taken up on the browser side and by the communication between server and browser. High Performance Web Sites covers every aspect of that process. Each performance rule is supported by specific examples, and code snippets are available on the book's companion web site. The rules include how to: Make Fewer HTTP Requests Use a Content Delivery Network Add an Expires Header Gzip Components Put Stylesheets at the Top Put Scripts at the Bottom Avoid CSS Expressions Make JavaScript and CSS External Reduce DNS Lookups Minify JavaScript Avoid Redirects Remove Duplicates Scripts Configure ETags Make Ajax Cacheable If you're building pages for high traffic destinations and want to optimize the experience of users visiting your site, this book is indispensable. "If everyone would implement just 20% of Steve's guidelines, the Web would be adramatically better place. Between this book and Steve's YSlow extension, there's reallyno excuse for having a sluggish web site anymore." -Joe Hewitt, Developer of Firebug debugger and Mozilla's DOM Inspector "Steve Souders has done a fantastic job of distilling a massive, semi-arcane art down to a set of concise, actionable, pragmatic engineering steps that will change the world of web performance." -Eric Lawrence, Developer of the Fiddler Web Debugger, Microsoft Corporation

Book excerpt: As the newfangled technology continues to invade the industry, more and more startups are joining the league and trying their ways with the latest innovations. Now a cutting-edge entry is Node.js which has not only pulled the startups but even carved its niche in the giant enterprises. It is seen that whenever there is a new wave in technology, the IT market raves about it for the first few months only to find it lost later, but let me tell you, Node.js stands fresh as an exception. Before we explain how Node.js is a game changer, let us understand what it is and how it works as best amongst its competitors.The Basics of Node.jsNode.js is an open source, cross-platform built on Chrome's JavaScript runtime for fast and scalable server-side and networking applications. Being an interface to the V8 JavaScript runtime, it enables event-driven programming to the web servers through super-fast JavaScript interpreter that runs in the Chrome browser.Non-Blocking I/O ModelNode.js works on a non-blocking I/O model that makes it clean and usable, ideal for the data-intensive real-time applications that have to perform in varied environments. Beating the conventional pattern, Node.js has bought a revolution in the development circle and has become the sought after option for brands like Yahoo, eBay, Walmart etc.The IoT phenomenon is also resorting to this platform for embedded devices and robotics like Cylon and Nodebots. Node.js empowers real-time web application by adopting push technology as against web sockets to build server-side web applications with two-way channel i.e. client and server. It operates on open web stack technologies like JavaScript, CSS, and HTML that work over the standard port 80. This tool is also lightweight both for in-memory usage and data-dense real-time web applications that work on multiple devices.Node.js Blessing For DeveloperUndoubtedly, Node.js is truly a blessing for a developer and must be taken to use by every enterprise. Take, for instance, chat applications which rule the market run on a lightweight, a speedy and high traffic model and should adopt Node.js to develop a data-friendly real-time application that works in various environments. Experts might object that the two-way channel has been present since long in the form of Java Applets or Flash, but in reality, they were redundant platforms using web transport protocol just to be circulated at the client side.Further, they were employed in non-standard ports and worked in isolation with the help of additional permissions. Node.js has proved to be a great milestone in IT market and has become a sure shot savior for heavy load web applications. Developers have got a swift move towards huge performance gains by giving the users advantage of end-to-end JavaScript experience and thus developing class apart real-time web applications.Still far from Node.js? If high performance and scalability, as well as short web development cycles, tempt you enough, it is high time you adopt Node.js. Here are some reasons that will convince you further-The Benefits1. The Fast SuiteCompanies are in awe of the speed at which Node.js functions. It runs on the V8 engine developed by Google that uses JavaScript into native machine code and operates at super speed. Node.js spares all the trouble involved with forming separate threads and instead uses a single thread, that is, the event loop that takes care of all the asynchronous I/O operations. Major actions in web applications including reading or writing to the database, network connections or file system can be performed quickly with this suite.Node.js empowers the organizations to create quick, robust network applications that can tackle parallel connections with increased throughput. It does not slow the working by any chance, but the developers need to be careful while writing the codes and the applications will get onto the right track....
