RSS FeedVellamo a bench marck in measuring various aspects of web browsing performance on: the part of the execution of JavaScript, User Experience, Networking. This project request by Qualcomm to improve its own software development. As one of the leading supplier Qualcomm chip has all contributions in the Android software ecosystem and Vellamo started as an internal tool for the performance gain in Qualcomm’s code to quantify.
Interestingly, Vellamo now available to the public. It is now available for download on Android Market and are expanding every 9 months or so. Let’s take a look at the four key performance indicators: Rendering: Rendering is the phase in which the browser does all the web-page data (HTML, CSS, JavaScript) and builds a real picture you can see. This is the key to web performance, as there are processing a lot of pixels on modern smartphones.
JavaScript: This is usually more important for Web applications, a series of codes to run the site interactive. Most sites are not very interactive (News, Wikipedia, Google), but sites like Mint and Google Docs are very interactive and earn the title of “web application”. Upcoming Web-based games Javascript extensively, although today, there are not many of them around.
User Experience: The things such as scroll speed and responsiveness page when users are scrolling and zooming. The idea is to be rebuilt at a certain level, some side blocks, and if they do not build fast enough, you can use parts of the blank page, or scroll nervous. If it is fast enough, the scrolling is smooth.
Networks: Of course, all the above information provided by the network, so it is extremely important that the network software layer is properly optimized. There are many strategies to improve the network, and many of them rely on the intelligent use of data in the cache (a local version), so network access as little as possible.
At the end of the test, the user gets a score, and even today Vellamo device similar to others in an online database. At the time the Galaxy Tab 10.1 sitting on top because the Honeycomb (Android 3.x) has many of the browser and JavaScript engine optimization. In the end, keep in mind that this is not measuring the speed of the hardware, but the whole system, enabling browsing (Internet hardware, software, optimizations …).
Of course one may wonder whether Qualcomm would measure its own chips to favor. It is reasonable to ask a question. Because the benchmark is an application like any other, Qualcomm chips in fact a competitor (believe me, you can create your own benchmark for subsequent bite in the ass) to lose. Qualcomm actually uses it internally, so it is best to work correctly … Finally, Qualcomm seen the release of the code to the public, and that’s probably the best way to gain legitimacy.
