UE4.10 NOT RESPONDING during importing assets.

Imported a LARGE number of materials.

Been watching task manager and it’s processing the files but ever so often UE will change to not responding for like 5 seconds then go back to responding. CPU is at 33% and Memory is staying at 34%.

Is this normal when moving around 2,000+ materials and meshes at the same time into UE?? Or is it my ****** comp that’s causing the issue??
