Cocos2d-x 3.0 Performance Benchmark

Cocos2d-x 3.0 Performance Benchamrk

This document is a brief introduction of testing sample and performance standard. I take this benchmark from two aspects-language compare and resource utilization compare.

Language Compare

This test is simply comparing the language performance by excuting Loop, Callback and MAT4. Take time consuming as the standard.

Loop:

N = 1000;
i = 0;
while(i < N)
{
	i++;
}

Callback:

N = 1000000;
i = 0;
sum = 0;
while(i < N)
{
	sum += add(i, 1);
}

N = 100000;
i = 0;
a = [...];
b = [...];
c = [...];
while(i < N)
{
	multiplayMatrix(a, b, c);
	i++;
}

Resource Utilization Comapre

This test is computing the memory consuming when adding 1000, 10000 and 100000 nodes in the scene.

N = 1000

i = 0

while(i < N)
{
	auto sprite = Sprite::create("HelloWorld.png");
	addChile(sprite);
	i++;
}
