ADO.NET :: Loading Dataset Using Datatabeladapter Crystal Reports?

I am trying hard to analyse but cant figured it out.I am using a Dataset which has 23 stored procedures (Table Adapters).Depending on the user requirement,I call each Tableadapter and pass the dataset to Crystal reports to display.

Namespace DAL
{
Dataset1 ds = new Dataset1();//Dataset instance is create/////
public dataset getdata()

{----

dataadapter.fill(ds1.sp1);

return ds;

}

public dataset getrecdata(params)

{---------

dataadapter.fill(ds1.sp2);

return ds;} and so on

}

Does the dataset instance gets loaded once or multiple times( as the table adapter calls each timme)Can anyone tell me if this is the right procedure I am following? and also does it work fast?or slows down my project.I am using dataset as input to Crystal reports bcaz thats working good in Design of crystal report as well as it takes dataset as input.
