尽管许多努力加速页面负载，但移动网络浏览仍然很慢。像其他人一样，我们发现客户端计算（尤其是JavaScript执行）是关键的罪魁祸首。但是，以前的解决方案可以减轻计算开销，但会遇到安全性，隐私性和可部署性问题，从而阻碍了他们的采用。为了避开这些问题，我们提出了一个基于浏览器的解决方案，其中每个客户端都从其先前的页面加载中重新进行相同的计算。我们在大约230页上进行的分析表明，即使在现代智能手机上，这种方法也可以减少最需要优化的页面中的49％的中位数。
Mobile web browsing remains slow despite many efforts to accelerate page loads. Like others, we find that client-side computation (in particular, JavaScript execution) is a key culprit. Prior solutions to mitigate computation overheads, however, suffer from security, privacy, and deployability issues, hindering their adoption. To sidestep these issues, we propose a browser-based solution in which every client reuses identical computations from its prior page loads. Our analysis across roughly 230 pages reveals that, even on a modern smartphone, such an approach could reduce client-side computation by a median of 49% on pages which are most in need of such optimizations.
