Tests B with 2000 and 2500 particles are faster than v0.9beta.
So, it seems that the particle engine is a little bit faster than previos versions.
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

Pure sprite tests seems to be faster than v0.8.2 probably due to:
SpriteSheet tets seems to perform at the same speed as v0.8.2
Except for tests G10,G11,G12 with 1000 and 1500 sprites that perform slower, I would say much slower, like 20% slower.
I'm still not sure why. It seems that it depends on the device. Sometimes it performs faster than v0.8.2, and sometimes like 20% slower.
