Is your application compliant with meego launcher? Are you sure this is the data that takes time to load and not the application itself?

Actually ,I come across the same problem in other OS ,such as Ubuntu 11.04,Fodera otc. Thanks.

I'm afraid that without knowing how your app works there is nothing I can suggest. If you share some code, I'll look at it and maybe I'll be able to suggest something.
