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

Note modest improvements on tcheck2 and ts. A new RSS regression was found with awsy.

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.

I am not including the actual graphs this month — there’s nothing very interesting to show.

tcheckerboard

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

0.00 (start of month) – 0.023 (end of month).

tcheck2

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

5.0 (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.

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.

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

tsvg_nochrome

Page load test for svg. Lower values are better.

4100 (start of month) – 4020 (end of month).

tp4m_nochrome

Generic page load test. Lower values are better.

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

tp4m_main_rss_nochrome

96000000 (start of month) – 95000000 (end of month).

Gradual improvements

tp4m_shutdown_nochrome

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

ts

Startup performance test. Lower values are better.

4000 (start of month) – 3400 (end of month).

ts_shutdown

Shutdown performance test. Lower values are better.

28000000 (start of month) – 28000000 (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.

This month’s graphs are incomplete (start late) due to maintenance on the phonedash system.

0213-throbber-start

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

0213-throbber-stop

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
