ParticleTest seems to be up ~15% slower than v1.0.0.

• A set randomly the position of the sprites. All the positions are inside of the screen
• B set randomly the position / scale of the sprites. All the positions are inside of the screen
• C set randomly the position / scale / rotation of the sprites. All the positions are inside of the screen
• D All sprites are rendered outside the screen
• E 80% of the sprites are positioned outside the screen. The other 20% is inside the screen
• F Perform transform Scale and Rotate actions to all sprites. 100% of the sprites inside the screen
• G Perform transform Scale and Rotate actions to all sprites. 20% of the sprites inside the screen

cocos2d 2.1 develop branch (28-11-2012). Test performed with device not connected to Xcode.

Sprite seems to pretty similar to v1.0.0. There are some exceptions where the performance seems to be a bit faster (2 or 3%), and other exceptions where the performances is slower (up to 10% slower)

Environment:

• iPod Touch 4th

ms: milliseconds, the lower the better.

Tests:

1. Test A: Iterate array of sprites using the Fast Enumeration API
2. Test B: Iterate array of sprites using the C API
3. Test C: Add %10 of the sprites in the spritesheet with different Z order
4. Test D: Remove %10 of the sprites from the spritesheet with different Z order
5. Test E: Reorder %10 in a spritesheet

Test not done yet.

These tests weren't performed in v2.0.0 It is believed that they perform as fast as in v1.0.0

How many bytes it takes to create an empty instance, without the possible inner mallocs.

cocos2d v2.0 takes less memory to create objects than v1.0
