我的ionic2應用程序需要15秒才能在設備中啓動。我嘗試了所有的建議（縮小，醜化，enableProd，--prod --release等） 我最後的APK是4.3MBIonic2性能問題
的應用程序沒有任何圖像除了從圖標，然後從splashcreen，它有更多的少20個屏幕，而只是文字和列表和按鈕（這是一個支付應用程序，所以沒有什麼奇怪）
我的package.json是：

你看到任何問題與相關性或與插件嗎？
最小化的main.js文件是5.8MB。

什麼建議嗎？你需要更多信息？這是我在Ionic2中的第一個應用程序，需要15秒才能加載。請幫助找到解決方案，我會投入大量時間在這個應用程序。

，我也面臨着同樣的issue.Wait的離子團隊發佈更新優化版本。他們正在研究它。 –
您是否有更多信息的鏈接？無論如何，有幾頁有建議（這對我來說不起作用），但也許是離子2.2.1的一個問題？你嘗試過更低的版本嗎？ – Faabass
