gingerbread slower as froyo but why?

Ive write a Rubiks Cube solver under froyo. For solving a random cube there will be generate several move - and pruning tables. All of them are save in an Array of type static short[][].

Normaly at first start of the Program under Froyo it will take about 90seconds to solve the Cube and 开发者_开发知识库then <3seconds.

Now ive update to gingerbread (2.3.4) and it is 10 times slower. But why? How is it possible? Any reason for this?

thanks..

I assume your goal is to make the app run fast on Gingerbread. Have you done any live debugging (e.g. with Traceview)? That would help identify exactly which methods are taking so long, and isolate the problem a bit more.
