= DE Performance page =
== UX & Performance team ==
* Communications
** IRC-channel #meego-arm at freenode
** DE daily meetings (time tbd)
** meego-handset mailing list
* Contributors
** Vesa-Matti Hartikainen IRC-nick: veskuh

== Problems ==

* Startup time of applications
* Startup time of the device
* Right after the homescreen has loaded, after the first boot, device is unusable for a while
* Memory use
* Slow I/O performance 2-20x slower than Maemo5 on N900
* UI scrolling freezes for 1-2s from time to time

== Task list ==
=== UX fixes ===
'''Tasks'''
* Collect bugs to metabug (Kristiine)
* Theming bugs
* Localization issues (Apps team)
* Close button for meego-ux based apps
* Remove systemui looking bar from meego-ux apps (it's confusing since it is not fully functional)

=== Reducing App Startup time ===
'''Tasks'''
* Investigate if booster really helps
* eMMC performance investigation, maemo is 2-20x faster? see [https://bugs.meego.com/show_bug.cgi?id=18295 bug #18295]
* last resort type of thing: taking NAND to use as swap (and destroying maemo installation)

'''Tasks Done'''
* eMMC vs. MMC, according to Sage, no major difference in old experiments

=== Reducing memory use ===
'''Tasks'''
* Remove unused applifed processes.
* lower GLES ParamBuffer size
* Merge meego-volume-control to systemui
* adjust stack sizes
* ramzswap trial

'''Tasks Done'''
* meego-ux to drop GL-context: https://bugs.meego.com/show_bug.cgi?id=18268

=== Improving first boot ===
'''Tasks'''
* tracker to preindex filesystem to improve first boot. see [https://bugs.meego.com/show_bug.cgi?id=18759 bug #18759]
* Reduce the number of .desktop files and icons meegohome scans at first boot
'''Tasks Done'''
=== Improving system startup ===
'''Tasks'''
* Reduce the list of [[ARM/N900/Performance/autostart|autostarted apps.]]
* Delay startup of dialer (by 30s)
* tracker configuration

'''Tasks Done'''

=== Improving UI Performance ===
'''Tasks'''
* Check if newer MTF improves performance
* Check if newer Qt improves performance
'''Tasks Done'''

=== Misc ===
'''Tasks'''
* optimizing MTF packages, there might be some configuration options, etc.?
* CGROUPS optimization, most likely still not done
* cache some often used data in NAND and symlink there
* test overclock with known testing (from qa-tools guys perhaps)
** kjokinie: Tested on my set up boot-times with some [[ARM/N900/Performance/OverclockBootTimeTest | overclock configurations]] already
*** practically it does not help at least boot time
*** however, at least audio player seemed much more responsive, so application performances should still be tested by QA.
* real microsdhc tests based on class speed rating
** actually answer specific questions about how write/read speed effect perf
*** app startup times
*** general usage
*** media write times
*** cataloguing media
* Swap on memory card (probably will not help if the os is on the card also, otherwise might)
* Taking fennec more frequently from upstream beta repository http://lists.meego.com/pipermail/meego-handset/2011-June/000467.html
* Profile startup of simple MTF, QML, and Qt apps
* Profile memory use of simple MTF, QML, and Qt apps
* Investigate configuration options for MTF
* Investigate configuration options for Qt
* Investigate configuration options for QML
* Update MTF (libmeegotouch, mcompositor, home, system ui, etc. ) to get latest optimizations from upstream
* Update Qt
'''Tasks Done'''
* Carsten tweaked kernel virtual memory settings (increased swappiness), Fennec bootup improved a lot and also system responsivness

== Benchmark results ==
* Results from Q/A http://wiki.meego.com/ARM/N900/QA/Performance
* Different class SD card benchmarking
** [[File:SDcard_benchmarking_060611.jpg]]
** Used image 05-30.1 acceptance image
** With class 10 card image worked really unstable. Measurements were got after several tries.
** Current class10 measurements are not comparable but give somekind of direction
* SunSpider (JavaScript performance
** 6.1s with GPE MiniBrowser (image DE.2011-05-30 acceptance)
** 6.8s with Fennec (image DE.2011-05-30 acceptance)
** These are actually pretty good results. Indicates that raw CPU perfomance is ok.

* Conclusion: meego-volume-control went down from 26000 kb to 3440 thanks for the qml ripout
* Can we reduce the mem usage of processes like sysuid, mdecorator, mthemedaemon
* Is booster-m really improving our performance as it takes itself a lot of from our memory that we do not have any extra without swapping?
** by removing the applauncherd (process starting booster-m) and tracker-store and delaying the dialer ui (40000 kb) launch by 30 second, bootup time will improved from 72 second to 59.

* Installation
1. download the tar from this page [http://wiki.meego.com/images/Bonnie_install.tar Bonnie++ v1.96] 
2. untar it in your device 
3. run install_bonnie.sh as root 

* Running tests with bonnie++
as root type following to start the standard test:
bonnie++ -u 0 > test_result
to view the result:
cat test_result
or if you don't need to store the result, just do
bonnie++ -u 0

=== Tips ===
* Testing conditions
** To achieve somewhat comparable results, let the device boot up fully before running the test
** Don't do anything else during the test, as this could impact the result.

=== TODO ===
1. Do an RPM package from Bonnie++ (current package is just cross-compiled binaries put manually in a tar...)
