Export/Import speed is super slow :(

So the problem is slow export process when using FBX for models over 3M and up triangles, takes 3-6 minutes or more if you have several heavy models. I’m interesting is there a way to speed up it. Actually I have found this topic https://developer.blender.org/T53236 and this one https://blender.community/c/rightclickselect/YKbbbc/ same.
Maybe we can push request somehow?
Many thanks!
