TMDB import to vodi wordpress theme is slow
I tried to import movies to the Vodi WordPress theme, but it is so slow, and sometimes it's not even completing the import.

Sorry but it is impossible to support third party programs.
There are hundreds.
Only the creators know which and how they built the API Requests.
Better to ask them for help directly.
