Adding parameters in cube and too much time connection to development server in psw

I am currently trying to create a cube through psw 3.9 version which i wanted to publish in BI server (version biserver-ce-5.2.0.0-209).

So i am facing 2 challenges

a)I am using Cygwin tunnel to connect to the development server database and while connecting it is taking too long time to create a schema or to create a cube.But for local machine database it works fine.Can this problem be resolved and how.

b)After creating cube i wanted to get the data based on some filter condition in BI dashboard.Like time_range,etc.How to add parameters in the cube or in BI server so user can select data based on date range

Please help me on this
