Saving on BI Platform is very slow

Hi all,

I have a Design Studio Application connected to 9 Datasources from BW. It's running on DS 1.3 SP2 and BI Platform 4.1 SP4. Saving the application to the BI Platform is very slow, it takes up to 15 minutes. Anyone has similar experiences, and/or a solution for this? It has some objects, and size of the content.biapp is 3.6MB.

Thanks!
