Before he left, Taras was discussing power consumption analysis with
Abram Hindle, a researcher at the university of Alberta. Some of
Hindle's work is here:
http://softwareprocess.es/static/GreenMining.html
Specifically this paper: "Green Mining: A Methodology of Relating
Software Change to Power Consumption"
http://softwareprocess.es/a/green-change-web.pdf
He's written a comparable paper targeting Fennec, and has interesting
preliminary findings. From his email to me:
"We found that blocking on a slow connection used consistently more
power than idle. This could be solely due to network traffic, but
network traffic was very periodic (1 packet in and 1 packet out per
second), thus much of the work could likely be attributed to the
animated spinner. The difference was not very large, but it was
statistically significant."
I spoke to him today at CSER, and despite Taras' departure he'd like to
continue this work that would give us a very fine-grained understanding
of where your battery's going, and which we could integrate into our
build infra.
So that's interesting. I'll forward his papers to you directly.
