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

No Talos regressions this month. RSS measurements are improving.

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.

0313tcheck

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

tcheck2

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

0313tcheck2

3.47 (start of month) – 3.47 (end of month).

trobopan

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

0313tpan

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

tprovider

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

0313provider

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

tsvg_nochrome

Page load test for svg. Lower values are better.

0313tsvg

4020 (start of month) – 4000 (end of month).

tp4m_nochrome

Generic page load test. Lower values are better.

0313tp

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

tp4m_main_rss_nochrome

0313tp-rss

95000000 (start of month) – 88000000 (end of month).

Several improvements

tp4m_shutdown_nochrome

0313tp-shutdown

28000000 (start of month) – 25000000 (end of month).

This “improvement” is bogus — see bug 797339.

ts

Startup performance test. Lower values are better.

0313ts

3400 (start of month) – 3800 (end of month).

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

ts_shutdown

Shutdown performance test. Lower values are better.

0313ts-shutdown

28000000 (start of month) – 25000000 (end of month).

This “improvement” is bogus — see bug 797339.

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).

This month’s graphs are incomplete (end early) but reflect the best data available at time of writing.

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

0313throbstart

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

0313throbstop

Eideticker

These graphs are taken from http://eideticker.wrla.ch. 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. More info at: https://wiki.mozilla.org/Project_Eideticker

awsy-mobile had a difficult month; we are re-generating the March graph data now. I’m going to skip these graphs this month since they are not quite ready yet.
