離子2：在啓動屏幕期間會發生什麼？

Question

我構建了一個Ionic 2應用程序，我想知道在應用程序啓動畫面期間發生了什麼精度？

即使在此啓動畫面期間，您是否可以建議我使用高效的分析工具來分析應用程序的所有性能？

我的應用程序在生產模式下，在6秒內初始化（榮譽6x專業版）。我覺得太多了，你覺得呢？

感謝您的幫助！

我的config.xml

我platform.ready功能：

platform.ready().then(() => { 
     StatusBar.styleDefault(); 
     Splashscreen.hide(); 
    });

建築用ionic build android --prod的伎倆。它大大減少了應用程序的初始化時間。
