Tracking time it took unity to import certain assets

Hey guys,

As you all know Unity allows importing different 3D file format such as FBX, Collada, OBJ, etc. I'm currently making a small research and comparison between different file formats. I would really appreciate if someone can tell me how can I track the time that it takes to import a certain object.

I initially wanted to use streaming assets but for that I need to write a custom parser for all the file formats, so it's not an option. Recourse.load is also not an option since it doesn't represent the actually time it took unity to import the file.

Basically, you know the bar unity shows when you drag a file in the project, the one that says "Importing small assets" I want to know how long it takes

Thank you in advance :)
