Consortium releases mobile browsing benchmark

A tool for measuring the processing and displaying of Web pages on mobile devices was recently released by the Embedded Microprocessor Benchmark Consortium (EEMBC).

The BrowsingBench analyses and measures the entire process of how Web pages are displayed in mobile devices, from selecting a URL to rendering a final page, providing a systems-level result that measures processors, as well as systems and applications software. In addition to measuring JavaScript execution, BrowsingBench also measures page-rendering speed and factors in content diversity.

"We developed BrowsingBench with a strong focus on real-world behavior by using real Web site content, connecting the Web server to the test device via wireless LAN and introducing client-server latency found on a typical Internet connection," explained Mansoor Chishtie, chief technologist of Web technologies at Texas Instruments and chair of the EEMBC group that developed the tool.

BrowsingBench sets up its own client-server network to ensure repeatability and a realistic broadband profile. It lets users modulate the bandwidth and latency of the local server to simulate a variety of wireless and WiFi scenarios, although the official test results will be generated using a standard 20ms latency to simulate a broadband profile.

The benchmark measures the actual browsing performance within a commercial stand-alone browser, as opposed to requiring custom applications for each device platform. Thus, the tool can be used to compare browsing performance across different hardware platforms running a wide variety of software browser implementations, according to EEMBC.

"Creating a benchmark for mobile platforms requires more than just loading a series of Web pages" said Shay Gal-On, EEMBC's director of technology and helped develop the tool. "You must carefully control caching effects, check for page-rendering compliance, and perform tasks such as page scrolling to ensure 100 percent rendering," he added.

"As an industry association, we also encourage manufacturers to join the working group to help define BrowsingBench 2.0," said EEMBC president Markus Levy.
