- now measuring APK size
- tcheck2 (temporarily) retired
- tsvgx and tp4m improved – thanks :jchen!
This quarter we began tracking the size of the Firefox for Android APK, and some of its components. You can see the size of every build on treeherder using Perfherder.
Here’s how the APK size changed over the last 2 months, for mozilla-central Android 4.0 opt builds:
There are lots of increases and a few decreases here. The most significant decrease (almost half a megabyte) is on Nov 23, from mfinkle’s change for Bug 1223526. The most significant increase (~200K) is on Dec 20, from a Skia update, Bug 1082598.
It is worth noting that the sizes of libxul.so over the same period were almost always increasing:
This section tracks Perfherder graphs for mozilla-central builds of Firefox for Android, for Talos tests run on Android 4.0 Opt. The test names shown are those used on treeherder. See https://wiki.mozilla.org/Buildbot/Talos for background on Talos.
We intend to retire the remaining Android Talos tests, migrating these tests to autophone in the very near future.
Measure of “checkerboarding” during simulation of real user interaction with page. Lower values are better.
An svg-only number that measures SVG rendering performance. About half of the tests are animations or iterations of rendering. This ASAP test (tsvgx) iterates in unlimited frame-rate mode thus reflecting the maximum rendering throughput of each test. The reported value is the page load time, or, for animations/iterations – overall duration the sequence/animation took to complete. Lower values are better.
730 (start of period) – 110 (end of period)
Generic page load test. Lower values are better.
730 (start of period) – 680 (end of period)
Note the same regression and improvement as seen in tsvgx.
Throbber Start / Throbber Stop
These graphs are taken from http://phonedash.mozilla.org. Browser startup performance is measured on real phones (a variety of popular devices).
Android tests are no longer run on Eideticker.
These graphs are taken from the mozbench dashboard at http://ouija.allizom.org/grafana/index.html#/dashboard/file/mozbench.json which includes some comparisons involving Firefox for Android. More info at https://wiki.mozilla.org/Auto-tools/Projects/Mozbench.
Sadly, the other mobile benchmarks have no data for most of November and December…I’m not sure why.
