Python - Overhead of `.so` Import?

I have 1000 custom (compiled into '.so') modules that I would like to use in pythonsimultaneously. Each such module has 100 [KB]an average size ( ).

Does anyone know what overhead (in the OS - if pythonnot processing this) of each import .so? Is the value overhead equal to the size of the file .soon disk? or is it fixed regardless of file size .so?

I haven't gotten there yet, but it would be interesting to know what affects the OS when you want to import, say, 10,000-50,000 custom modules at the same time.
