Hi Rommel,
There are several things that could be effecting the performance of your form. what versions of SharePoint and InfoPath are you using?
Here are some things to consider:
1. View Length (How much the user has to scroll in a view)
2. Size of your Template
3. When you query your data
4. If your query is filtered or not
5. Large images in your view
Hope that helps!
