Demystifying the Imperfect Client-Side Cache Performance of Mobile Web Browsing

A survey of techniques for improving efficiency of mobile web browsing

“…Liu et al studied performance issues related to client‐side caching and proposed strategies to address them. By crawling resources from several websites at a fine granularity of time, their technique finds the resource update history and cache configurations at the server end.…”

“…An example JS code which shows that attaching random strings to URLs leads to fetching the same content from different URLs…”

“…Table 8 summarizes the techniques for reducing PLT. Study on the effectiveness of web caching 3,28,42 Study on the cacheability of different resources 67,80 Setting the expiration time in browser cache 3,32,42,80 Caching of style formatting, 36 microcaching (ie, caching of few CSS rules, HTML elements, and few JS lines) 67 Prefetching [26][27][28] Speculative loading 15,28 MPTCP 31,43,56 Using multiple connections to fetch webpage contents in parallel 17,28,30 Stopping rate throttling when the user touches the screen 51 Placing stable web resources in a package and loading them locally from the device 35 Graph-based modeling of the webpage structure 28,32,36…”

“…(3) The benefit of MPTCP diminishes (a) on using a small page size, (b) when the latency/throughput properties of the secondary path are inferior to those of the primary path, or (c) when local computation and not network communication is the bottleneck. 56 Formats for reducing image sizes WebP, 29,33 JPEG 25,54 Avoiding redundant download/transfer 32,35,42,80 Sending higher-quality version as ''delta'' 25 Adapting the website content to the user's cost budget 66 Ignoring minor updates of the webpage 61 Ad-aware management 41,57,74,84,85 Avoiding third-party services 3,54 Han et al 56 noted that in the ''request-response'' resource-fetching approach of HTTP, the resources are iteratively discovered and fetched.…”

“…Some works exclude websites that use HTTPS, 33,80 whereas others consider only the landing pages of each website. 3,58,80 These studies may not be representative of the full spectrum of websites and webpages. Similarly, most works evaluate the energy saving or performance improvement without measuring the QoE or satisfaction of the end user.…”
