高通提供了一个adreno gpu上的性能分析工具，可以直接分析[Android][] / PC上opengles应用程序的性能。

### AdrenoProfiler(v3.0.1) ###

### 实验 ###

软件具体使用看帮助文档，

1. 打开手机上opengles开发的应用程序

2. 打开软件，点击connect

3. new 一个 grapher页面，然后在右边树状列表中双击打开相应视图，常用的是Grapher Metrics 下的**EGL / FPS**和**GPU General / Busy**

实测：

数据量：

03-01 15:46:29.482: I/VBO(10518): position size = 1458000

03-01 15:46:29.482: I/VBO(10518): normal size = 1458000

03-01 15:46:29.482: I/VBO(10518): texture size = 972000

HTC G10上实测，当顶点、法线、纹理数据量均在1M左右时 vertex array和vbo才能有明显区别。

如上图，采用VBO绘制，FPS在50左右，GPU Busy在100%左右；当切换到vertex array时fps在30左右，GPU Busy在80%左右。
