Performance Issue on assemblies

Hello. I have soliworks 2017 premium on my computer.

I have an assembly with about 30 parts and some in context relations.

Whenever I want to edit a sketch on a component on the assembly, or delete a part, I have to wait about 2 to 3 minutes to Soliworks to rebuild and so on and I am starting to get a bit frustated about this, because I only have some parts related to others. I have big assembly mode on, tried lightweight mode, tried to suspend rebuild on the system properties (solidworks rebuild anyways) and I think I will stop using solidworks if I dont get this solved, because it is not efficient.

MY computer specs are:

i7 6700HQ

Nvidia GTX 960M

Any help is good thanks.
