Optimization of Blender Importing FBX Large Files

May I ask if Blender will optimize the default FBX import plugin? When I import FBX files over 150M (with around 40000 models and 600000 triangles), the Blender interface always freezes for a long time or has no response. Now Blender is really slow when importing large file models. I hope to get optimized or add a prompt to display the progress of model import, otherwise I really can't distinguish whether Blender is working or has crashed and stuck TVT
