My monthly review of Firefox for Android performance measurements. March highlights:

– 3 throbber start/stop regressions

– Eideticker not reporting results for the last couple of weeks.

Talos

This section tracks Perfomatic graphs from graphs.mozilla.org for mozilla-central builds of Native Fennec (Android 2.2 opt). The test names shown are those used on tbpl. See https://wiki.mozilla.org/Buildbot/Talos for background on Talos.

tcanvasmark

This test runs the third-party CanvasMark benchmark suite, which measures the browser’s ability to render a variety of canvas animations at a smooth framerate as the scenes grow more complex. Results are a score “based on the length of time the browser was able to maintain the test scene at greater than 30 FPS, multiplied by a weighting for the complexity of each test type”. Higher values are better.

7200 (start of period) – 6300 (end of period).

Regression of March 5 – bug 980423 (disable skia-gl).

tcheck2

Measure of “checkerboarding” during simulation of real user interaction with page. Lower values are better.

24 (start of period) – 24 (end of period)

trobopan

Panning performance test. Value is square of frame delays (ms greater than 25 ms) encountered while panning. Lower values are better.

110000 (start of period) – 110000 (end of period)

tprovider

Performance of history and bookmarks’ provider. Reports time (ms) to perform a group of database operations. Lower values are better.

375 (start of period) – 425 (end of period).

Regression of March 29 – bug 990101. (test modified)

tsvgx

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.

7600 (start of period) – 7300 (end of period).

tp4m

Generic page load test. Lower values are better.

710 (start of period) – 750 (end of period).

No specific regression identified.

ts_paint

Startup performance test. Lower values are better.

3600 (start of period) – 3600 (end of period).

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).

3 regressions were reported this month: bug 980757, bug 982864, bug 986416.

:bc continued his work on noise reduction in March. Changes in the test setup have likely affected the phonedash graphs this month. We’ll check back at the end of April.

Eideticker

These graphs are taken from http://eideticker.mozilla.org. Eideticker is a performance harness that measures user perceived performance of web browsers by video capturing them in action and subsequently running image analysis on the raw result.

Eideticker results for the last couple of weeks are not available. We’ll check back at the end of April.
