  • Geometry Batching ...
    28854be7 
    A reduction in GL calls can be observed when running the example with the following options for comparison:

DALI_GLES_CALL_TIME=1 DALI_GLES_CALL_TIME_ACCUMULATE=1 homescreen-benchmark.example –disable-icon-labels
&
DALI_GLES_CALL_TIME=1 DALI_GLES_CALL_TIME_ACCUMULATE=1 homescreen-benchmark.example –disable-icon-labels –disable-batching

                 W/O Batching      W/ Batching     % Improvement
Bind buffers       0.00             11.88             N/A
Bind textures      4.03              5.6             -26%
Draw calls        27.31             10.06            +63%
Uniform sets      53.88             10.06            +81%

Note: Larger improvements can be seen when the bottleneck is within the Render thread (instead of Update).

  • Improve application launching speed ...
    24c8baf6 
    To improve app launching speed on Tizen (using launchpad), Use -fPIE option instead -fPIC and attach DALI_EXPORT_API in front of each example's main function.

This is the compare result between before and after patch.
(On hawkP 2.4 / using hello-dalidemo that has one pushbutton on stage)

|    before Patch     |     After Patch     |
---------------------------------------------
|   hello-dalidemo    |   hello-dalidemo    |
---------------------------------------------
|   AVG   MIN   MAX   |   AVG   MIN   MAX   |
|  1134  1060  1188   |   291   250   337   |

After patch, launching speed drops to 30% of before.
