Datazilla

This page details Datazilla and how we use it to triage performance problems in Firefox OS.

Collection

Data in Datazilla is collected from automated tests. Some of these tests reside within gaia in tests/performance, and there are also python tests on github in the b2gperf repo. There is a jenkins instance in Mountain View which runs the automated tests.

Current Tests

Cold Load Time: Does what now? Startup Time: Does what now?

Triaging Regressions

Each point in datazilla has a gaia, gecko, and platform build revision id. You can use this information to triage and locate where the regression occurred. One way of doing this is to use the B2G profiler: https://github.com/mozilla-b2g/B2G/blob/master/profile.sh
