度量以計算和比較Android中的RAM和CPU使用情況

Question

我有兩個版本的Android，我正在設備上測試，兩者在AOSP中的少數服務上有所不同。我想進行一些基準測試，看看新的系統服務消耗了多少內存和CPU使用量。我不知道如何開始。是否有任何現有的基準達到相同？如果不是，我應該如何繼續在這種情況下。

任何幫助，通過

你可以運行一些我的CPU和內存基準測試（免費的，沒有增加），你可以從谷歌安裝Android終端模擬器遊戲和使用Linux命令進行top或vmstat監視所使用的資源（至少它們可以在我的平板電腦上運行）。

下面是從vmstat運行我的一個基準測試的細節。

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.
