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

Note: Cold startup for Galaxy Nexus was unavailable — here are the results for LG-P999 instead.
