AFAIK there are two ways to profile an app: *'profile.sh'* - Build a custom B2G with the `MOZ_PROFILING=1` flag and use `profile.sh` script in the B2G repo.
A very labour intensive process, taking hours to prepare for. The results are hard to interpret, that only a few Gecko engineers seem to to be able to derive meaning from. *'Devtools*' - Use the devtools 'Performance' profiler via WebIDE. Seems to crash the app being profiled and leaves the devtools unresponsive. --- Am I missing something here? Happy to update MDN or provide material to help others in the future once I have reached enlightenment :) *W I L S O N P A G E* Front-end Developer Firefox OS (Gaia) London Office Twitter: @wilsonpage IRC: wilsonpage
