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）

performance com.xueqiu.android
%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
