In a Django web application, would large files or many unnecessary import statements slow down my server?
Views load only one time, at the moment of start your code
In my Django web app, I have pretty much one large file that contains all my views.  This has a ton of imported python libraries that are only used for certain views.  
Does this slow my code?  Like in python does importing things like python natural language toolkit (nlkt) and threading libraries slow down the code when its not needed?
I know its not great for a maintainability/style standpoint to have one big file like this, but I am asking purely from a performance standpoint.
