That is great to hear Lucas! (the deploy part), for the import files would be great to get more details on the case. Continue working with it, and if you see that the "long time" is persistent and is being a pain, feel free to raise an Issue in GitHub and add details to track it properly 🙂.
We are aware of a performance improvement opportunity to interact with the File Cabinet, so is on my radar but we haven´t start that implementation yet.
