“…We observe that a large fraction of resources is not pushable as they reside on other servers. Moreover, many websites depend on third-party content-impacting the loading process [13,16]. Also, not many sites benefit from a push all strategy.…”

“…Although assessing the performance of Server Push in real-world deployments [23,26,35,39] is crucial, it imposes practical challenges. Among other factors, websites i) can change due to dynamic thirdparty content, e.g., ads [16], or ii) are subject to varying network characteristics. This can cause misinterpretations of the results.…”

HTTP/2 supersedes HTTP/1.1 to tackle the performance challenges of the modern Web. A highly anticipated feature is Server Push, enabling servers to send data without explicit client requests, thus potentially saving time. Although guidelines on how to use Server Push emerged, measurements have shown that it can easily be used in a suboptimal way and hurt instead of improving performance. We thus tackle the question if the current Web can make better use of Server Push. First, we enable real-world websites to be replayed in a testbed to study the effects of different Server Push strategies. Using this, we next revisit proposed guidelines to grasp their performance impact. Finally, based on our results, we propose a novel strategy using an alternative server scheduler that enables to interleave resources. This improves the visual progress for some websites, with minor modifications to the deployment. Still, our results highlight the limits of Server Push: a deep understanding of web engineering is required to make optimal use of it, and not every site will benefit.

“…We use the independent filter lists from https://filterlists.com to build the list of targets. We focus on ad services because this type of third party services inflate significantly performance metrics of web services (e.g., page load time), as well as impact the web experience of mobile users [14]. Thus, it is important to captute (and potentially eliminate) any additional delay penalty that might impact how fast a roaming user receives this type of content.…”

Roam like Home" is the initiative of the European Commission (EC) to end the levy of extra charges when roaming within the European region. As a result, people are able to use data services more freely across Europe. However, the implications roaming solutions have on performance have not been carefully examined. This paper provides an in-depth characterization of the implications of international data roaming within Europe. We build a unique roaming measurement platform using 16 different mobile networks deployed in six countries across Europe. Using this platform, we measure different aspects of international roaming in 3G and 4G networks, including mobile network configuration, performance characteristics, and content discrimination. We find that operators adopt common approaches to implementing roaming, resulting in additional latency penalties of ∼60 ms or more, depending on geographical distance. Considering content accessibility, roaming poses additional constraints that leads to only minimal deviations when accessing content in the original country. However, geographical restrictions in the visited country make the picture more complicated and less intuitive.

“…"Web bloat" is a colloquial term that describes the trend in websites to accumulate size and visual complexity over time. The phenomena has been measured in many dimensions, including total page size [7], page load time [5,43,44], memory needed [29], number of network requests [16,27], amount of scripts executed [25,33,36,38] and third parties contacted [24,25,27]. This work suggests that growth in page size and complexity is outpacing improvements in device hardware.…”

Most popular web browsers include "reader modes" that improve the user experience by removing un-useful page elements. Reader modes reformat the page to hide elements that are not related to the page's main content. Such page elements include site navigation, advertising related videos and images, and most JavaScript. The intended end result is that users can enjoy the content they are interested in, without distraction.In this work, we consider whether the "reader mode" can be widened to also provide performance and privacy improvements. Instead of its use as a post-render feature to clean up the clutter on a page we propose SpeedReader as an alternative multistep pipeline that is part of the rendering pipeline. Once the tool decides during the initial phase of a page load that a page is suitable for reader mode use, it directly applies document tree translation before the page is rendered.Based on our measurements, we believe that SpeedReader can be continuously enabled in order to drastically improve end-user experience, especially on slower mobile connections. Combined with our approach to predicting which pages should be rendered in reader mode with 91% accuracy, it achieves drastic speedups and bandwidth reductions of up to 27× and 84× respectively on average. We further find that our novel "reader mode" approach brings with it significant privacy improvements to users. Our approach effectively removes all commonly recognized trackers, issuing 115 fewer requests to third parties, and interacts with 64 fewer trackers on average, on transformed pages.
