The April 2013 summary of performance measures for Firefox for Android.

Minor regressions in tcheck2 and tp4m. Slight improvement in “time to throbber stop”.

Talos

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

tcheckerboard

Simple measure of “checkerboarding”. Lower values are better.

0.0 (start of month) – 0.0 (end of month).

tcheck2

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

3.5 (start of month) – 4.0 (end of month).

Bug 866113 – Talos Regression tcheck2 26% on Android 2.2, Apr 26

trobopan

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

12000 (start of month) – 14000 (end of month).

There is noise in this test; it’s not clear if there was an actual regression this month.

tprovider

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

375 (start of month) – 375 (end of month).

tsvg_nochrome

Page load test for svg. Lower values are better.

4000 (start of month) – 3800 (end of month).

tp4m_nochrome

Generic page load test. Lower values are better.

720 (start of month) – 780 (end of month).

Bug 864637 – 11% Android Tp4 NoChrome regression on 2013-04-18

tp4m_main_rss_nochrome

88000000 (start of month) – 90000000 (end of month).

Gradual regression — no bug.

tp4m_shutdown_nochrome

25000000 (start of month) – 25000000 (end of month).

ts

Startup performance test. Lower values are better.

3800 (start of month) – 3800 (end of month).

ts_shutdown

Shutdown performance test. Lower values are better.

25000000 (start of month) – 25000000 (end of month).

Throbber Start / Throbber Stop

These graphs are taken from http://mrcote.info/phonedash/#/.  Browser startup performance is measured on real phones (a variety of popular devices).

“Time to throbber start” measures the time from process launch to the start of the throbber animation. Smaller values are better.

“Time to throbber stop” measures the time from process launch to the end of the throbber animation. Smaller values are better.
