Web Browsing Measurements: An Above-The-Fold Browser-Based Technique
Résumé
Web browsing is the most important Internet service,
and offering the best performance to end-users is of
prime importance. The World Wide Web Consortium (W3C)
has brought along the Page Load Time (PLT) metric as a
QoE (Quality of Experience) and QoS (Quality of Service)
benchmarking indicator, which is nowadays the de facto web
metric used by researchers, large service companies and web
developers. Although alternative web metrics have been introduced
to measure part of the loading process, the techniques used
need additional computing power and timings are not offered
in real-time. In order to provide real-time fined-grained timings
during web browsing measurement campaigns, we present in this
paper the TFVR (Time for Full Visual Rendering), a technique
being browser-based to calculate the Above-The-Fold (ATF)
offering the loading time of the visible portion at first glance
of a web page. The TFVR exposes fine-grained timings such as
networking and processing time for every downloaded resource.
Based on a measurement campaign on top 10,000 Alexa websites,
we have been able to better quantify and identify web page
loading inefficiencies through a tool we have designed, namely,
MORIS (Measuring and Observing Representative Information
on webSites).
