  This paper examines some of the potential challenges associated with enabling
a seamless web experience on underpowered mobile devices such as Google Glass
from the perspective of web content providers, device, and the network. We
conducted experiments to study the impact of webpage complexity, individual web
components and different application layer protocols while accessing webpages
on the performance of Glass browser, by measuring webpage load time,
temperature variation and power consumption and compare it to a smartphone. Our
findings suggest that (a) performance of Glass compared to a smartphone in
terms of power consumption and webpage load time deteriorates with increasing
webpage complexity (b) execution time for popular JavaScript benchmarks is
about 3-8 times higher on Glass compared to a smartphone, (c) WebP is more
energy efficient image format than JPEG and PNG, and (d) seven out of 50
websites studied are optimized for content delivery to Glass.
