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
Benchmark results
- Results from Q/A http://wiki.meego.com/ARM/N900/QA/Performance
- Different class SD card benchmarking
-
- 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.
- widgetsgallery -timedemo -log-fps

- 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
Improvement ideas
- optimizing MTF packages, there might be some configuration options, etc.?
- ramzswap trial
- CGROUPS optimization, most likely still not done
- eMMC performance investigation, maemo is 2-20x faster? see bug #18295
- last resort type of thing: taking NAND to use as swap (and destroying maemo installation)
- adjust stack sizes
- lower GLES ParamBuffer size
- Remove unused applifed processes.
- Merge meego-volume-control to systemui
- cache some often used data in NAND and symlink there
- tracker configuration
- test overclock with known testing (from qa-tools guys perhaps)
- 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
- actually answer specific questions about how write/read speed effect perf
- Swap on memory card (probably will not help if the os is on the card also, otherwise might)
- Reduce the list of autostarted apps.
TODO list
- 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
