Check the parts Feature Statistics and look at the time(s) listed.
Make a de-featured configuration of the parts with the longest rebuild times. To de-feature suppress what you dont need in the assembly (eg. fillets chamfers...etc). Update the assembly to use those new de-featured configurations.

You can do all the lightweight parts (icon is presented with a pen next to the name part), or use speedpack (a useful feature in low and when the computer does not need internal parts), and of course a very truncated configuration details (repayment of facets, some fillets, holes, etc. etc.) - is useful in calculations and simulations

try as much as you can to eliminate any unnecessary degree of freedom.
few top level components, more subassemblies, reduce the quality of appearance, save it as a one part.
with sw2012, you can freeze rebuild.

I have created an add-in that will do the job for you and go beyond SolidWorks standard functionality. More info: www.swap3d.com

You're going to lose any functionality, but solve as rigid for assemblies with multiple subassemblies works pretty well. This is a way "in SolidWorks" to simplify an assembly.

To answer the asked question, THEE best way to simplify an "assembly in SolidWorks" would be:
A) Buy a better computer
