Performance Android中计算和比较RAM和CPU使用率的指标

我在一台设备上测试了两个版本的Android，它们在AOSP中的一些服务上都有所不同。我想做一些基准测试，看看新的系统服务消耗了我多少RAM和CPU使用量。我不知道如何开始。是否有任何现有的基准达到同样的目标？如果没有，我应该如何处理这个问题

非常感谢您的帮助

您可以通过

此外，您还可以从Google Play安装Android终端仿真器，并使用Linux命令for top或vmstat来监控所使用的资源（至少它们可以在我的平板电脑上工作）

下面是运行我的一个基准测试时来自vmstat的详细信息

Command vmstat -d 1 -n 60 > /mnt/extsd/vmst3.txt
For 60 samples of one second to txt file on external SD card
via path as identified by the df command
Command cat /mnt/extsd/vmst3.txt to display details

Start this, switch to main display, execute MemSpeed.apk that uses up
to 65 MB over nearly 11 seconds (starts in 16 seconds after a bit of 
fiddling that uses some system CPU time). Note free memory reduction 
and 99% CPU utilisation for 10+ seconds. Idle time is clearly wrong.
