Can a lot of functions in one controller file slows down the whole thing?

Hello everyone,
I need to know something. Assume we put a lot of functions in controller for MVC. What is the best practice for system efficiency? Should I put them in different controllers or keep them inside one controller? Can putting so many functions in one controller class makes things slower?

Yes it can make it slow down, but you would not really notice it with the speed of servers now days.

You can put them in a helper or or a class library, if they are for database access then place them into the model.
