性能获取办法

appium+webview context + execute script +perfmance api
appium/selenium的ExecuteScript Api
注入js:
return JSON.stringify(window.performance.timing)
JSON.stringify(window.performance.getEntriesByName(document.querySelector("img").src[0],null,2)

%CUP:cup使用率
%MEM:内存占用率
RES:申请使用的内存(进程占用的物理内存)
SHR:进程使用的共享内存

获取详细内存

adb shell dumpsys meminfo com.xueqiu.android | grep "Native Heap" | head -1
pss:按比例共享内存(实际内存+部分共享内存)
Private Dirty:仅分配给您的应用堆的实际RAM 用来判断内存泄漏,如果内存泄漏,这个值会变大
手机端的性能主要是:耗电量,内存泄漏,cpu,卡顿,崩溃
