My simple question is : Does multiple table join slows down mysql performance?

I have a data set where I need to do about 6 tables JOIN, on properly indexed columns.

I read the threads like

Join slows down sql MySQL adding join slows down whole query MySQL multiple table join query performance issue

But the question remains still as it is.

Can someone who experienced this thing reply?
