Rhino8 performance when opening autocad drawings

Is there some trick I can use to improve performance when opening relatively big AutoCAD drawings in Rhino?
Every action, being it, hide, pan the screen, zoom selection takes a couple of seconds and more to do.

This is terrible!

It just sucked in half my RAM using 0.1% CPU.
I feel SSD caching is not used at all?
Can it be? Will it help?
