SolidWorks slow to rebuild small assemblies

Hello,

I'm working on a small assembly with around 50 components and solidworks is very slow to rebuild model especially since I've added few holes with the drilling assistant. I have only this assembly openned and my laptop is brand new with an Nvidia GeForce GTX 1650 and 16Go RAM. It takes around 15-20 seconds each time I edit a function or I rebuild the assembly. Moreover, after the rebuild, there are some "rebuild traffic lights" which stay on some parts or assemblies. They never disapear even is I rebuild again and again.

I don't what to do to improve the performance and reduce this time lost each time. I tried to reduce the graphic performance but the problem is still there...

Thank you for your help.
