  This study takes a close look at mobile web performance. The two main
parameters determining web page load time are the network speed and the
computing power of the end-user device. Based on data from real users, this
paper quantifies the relative importance of network and device. The findings
suggest that increased processing power of latest generation smart phones and
optimized browsers have a significant impact on web performance; up to 56%
reduction in median page load time from one generation to the following. The
cellular networks, on the other hand, have become so mature that the median
page load time on one fiber-to-the-home network (using wifi for the last meter)
is only 18-28% faster than cellular and the median page load time on one DSL
network is 19% slower compared to a well-deployed cellular network.
