long rebuilt time

I am working on the drawing of large assembly and whenever i switch my sheet from 1 to 2 or 2 to 3 it takes more than 15- 20 minutes to get me on next page. Is there any way I can make it faster or reduce the model size, because in my model i got more than 2000 surface bodies of one part.I tried enable freeze bar option but its not really working for me Any help would be appreciated.
