Mobile devices have become the primary mode of Internet access. Yet, differences in mobile hardware resources, such as device memory, coupled with the rising complexity of Web pages can lead to widely different quality of experience for users. In this work, we analyze how device memory usage affects Web browsing performance. We quantify the memory footprint of popular Web pages over different mobile devices, mobile browsers, and Android versions, analyze the induced memory distribution across different browser components (e.g., JavaScript engine and compositor), investigate how performance gets impacted under memory pressure and propose optimizations to reduce the memory footprint of Web browsing. We show that these optimizations can improve performance and reduce chances of browser crashes in low memory scenarios.

内存压力下的移动网页浏览

移动设备已成为互联网接入的主要方式。然而，移动硬件资源（例如设备内存）的差异，加上网页复杂性的提高，可能会导致用户体验质量大相径庭。在这项工作中，我们分析了设备内存使用如何影响 Web 浏览性能。我们量化了流行网页在不同移动设备、移动浏览器和 Android 版本上的内存占用，分析了不同浏览器组件（例如 JavaScript 引擎和合成器）之间的诱导内存分布，研究了在内存压力下性能如何受到影响并提出优化建议以减少 Web 浏览的内存占用。我们表明，这些优化可以提高性能并减少低内存情况下浏览器崩溃的机会。
