User quality of experience in the context of Web browsing is being researched widely, with plenty of developments occurring alongside technological advances, not seldom driven by big industry players. With the huge reach and infrastructure of Google, the Chrome User Experience Report (CrUX) provides quantitative real-life measurement data of a vast magnitude. Analysis of this steadily expanding dataset aggregating different user experience metrics, yields tangible insights into actual trends and developments. Hence, this paper is the first to study the CrUX dataset from the viewpoint of relevant metrics by quantitative evaluation of users Web browsing experience across three device types and nine European countries. Analysis of data segmented by connection type in the device dimension shows desktops outperforming other device types for all metrics. Similar analysis in the country dimension, shows North European countries (Sweden, Finland) having maximum 4G connections (85.99%, 81.41% respectively) and steadily performing 25%-36% better at the 75th percentile across all metrics compared to the worst performing country. Such a high-level longitudinal analysis of real-life Web browsing experience provides an extensive base for future research.

翻译：网页浏览中的用户质量体验正被广泛研究，许多发展伴随技术进步而涌现，其中不乏大型行业巨头的推动。凭借谷歌庞大的覆盖范围和基础设施，Chrome 用户体验报告（CrUX）提供了规模巨大的定量真实测量数据。对这份持续扩展、聚合不同用户体验指标的数据集进行分析，能得出对实际趋势和发展的具体洞察。因此，本文首次从相关指标视角，通过定量评估用户在三类设备和九个欧洲国家的网页浏览体验来研究 CrUX 数据集。对设备维度中按连接类型细分的数据分析显示，台式机在所有指标上均优于其他设备类型。对国家维度中的类似分析表明，北欧国家（瑞典、芬兰）拥有最多的 4G 连接（分别为 85.99%、81.41%），且在第 75 百分位上的所有指标中，其表现稳定比性能最差的国家高出 25%-36%。这种对真实网页浏览体验的高层次纵向分析为未来研究提供了广泛基础。
