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

Few significant changes this month. Some improvement in “time to throbber start”.

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.

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.

4.0 (start of month) – 3.8 (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).

There was a regression in this test during the month (June 12 – 24) — see bug 882120.

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.

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

This was caused by a change to the test infrastructure — see bug 883894.

tp4m_nochrome

Generic page load test. Lower values are better.

680 (start of month) – 590 (end of month).

Slight improvement on June 19 (bug 883894 again?).

tp4m_main_rss_nochrome

125000000 (start of month) – 128000000 (end of month).

Expected regression here, on June 26 — see bug 878674.

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://phonedash.mozilla.org. 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.

Note the recent improvement.

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

See Bug 879357 – Regression in “time to throbber stop” on May 31 — Nexus One and Droid Pro only

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.

It seems we are not slim yet!
