MonoDroid速度

Question

我正在考慮轉向MonoDroid，問題是試用版只允許在模擬器中測試我的代碼，並且一切在模擬器中運行緩慢。我的問題（在我支付400美元之前）是否編譯後的代碼在部署到實際設備時運行得足夠快？

Answer 1

在應用程序啓動後（〜3s），性能在Nexus One上非常好，而且與在仿真器上運行完全不同。

Answer 2

設備上的性能對我也有好處。有時甚至比Dalvik還快。但是，是的，開始時存在2-3秒的延遲。

（這個「答案」旨在保證誰願意嘗試MonoDroid的，它的作品不僅是一個人:)人）

Answer 3

我看到的啓動遠遠超過2-3秒的滯後。也就是說，從我點擊應用程序（並且日誌顯示ActivityManager開始我的活動）到第一次調用OnCreate時的時間。

我在Android 2.2（約2歲）的HTC Legend上看到5秒或更長的時間。例如：

2011-11-26 11:54:37.782 I 97/ActivityManager: Displayed activity 
com.xxx.android/.SplashActivity: 5309 ms (total 5309 ms)

Answer 4

的緩慢是由於Android模擬器 - 在實際設備上運行的是罰款MonoDroid的。
