Hi all,

  I’ve ported android 2.2 to my board, but I found that android 2.2 UI is
slower than android 1.6. For example, android 2.2 UI keypad response time is
longer than android 1.6. When I click the left button my board, it takes
500ms for android 2.2 to response it, but in android 1.6 it is responded
immediately. I’ve printed log in my keypad driver, it seems that my keypad
event is captured immediately in driver, but it takes 500ms for android UI
to response it. I don't what android is doing in the 500ms. I think the
problem should be android "fade in fade out" UI feature, but how can I
disable the feature? Or does anybody have the same problem? Any help is
appreciated, thanks.

ps: my board runs on arm 926t with 128M SDRAM.
