“GL” test部分模块 内存占用测试

trunk 3.0 #90770

测试机型：N5 6.0

dump场景：

  1. 正常运行——静置3min
  2. 进入负一屏
  3. 进入3D时钟
  4. 进入AllApps
  5. 进入天气
  6. 进入搜索
  7. 应用3D主题之后
  8. 3D主题关屏之后
  9. 从3D切回2D

测试结论

以下结论基于N5 6.0机型，结果未与其它机器、安卓版本做横向比较

  • test进程内，各模块切换时未出现太大波动
  • 但test起始值（Gfx dev）在 40000KB（~40M）左右，考虑这一点是否有改进必要、空间？
  • 3D主题相较2D，内存占用升高~17M左右（具体值未严格测试）
  • 关屏之后（静置>2min），未对内存占用做优化处理——考虑是否可行？是否必要？？？
  • 从3D切回2D，内存反增11M左右（对此dump文件感兴趣的同学联系我）——此处需要分析hprof，找到问题点

实验数据

正常运行——静置3min
