I skipped my regular February post and I am thinking of writing up these performance summaries less frequently — maybe every 2 or 3 months. Any objections?

Highlights:

– Talos trobopan, tprovider, and ts tests have been retired.

– Big improvement in tsvgx.

Talos

This section tracks Perfomatic graphs from graphs.mozilla.org for mozilla-central builds of Firefox for Android, for Talos tests run on Android 4.0 O. The test names shown are those used on treeherder. See https://wiki.mozilla.org/Buildbot/Talos for background on Talos.

tcheck2

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

18.7 (start of period) – 19.0 (end of period)

trobopan

This test is no longer run.

tprovider

This test is no longer run.

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.

svg

3500 (start of period) – 720 (end of period).

Big improvements Feb 26 and March 6. The March 6 improvement seems to have been caused by a Talos update.

tp4m

Generic page load test. Lower values are better.

710 (start of period) – 680 (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).

Time to throbber start seems steady this month.

throbber-start

Time to throbber stop has some small improvements and regressions.

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.

mozbench

I recently discovered 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.
