Dynamic Link and Skyrocketing Renders

Hi, I am trying to render a project using Adobe Premiere's Great Dynamic Link, but render times are skyrocketing when I use this feature so I am backtracking myself by going back into after effects and rendering all these files I have learned that if you just send all the clips to AE you will just have all these clips separated (Is this True) and how do you slow down render times is it due to the fact that I essentially overloaded my project with too many AE Comps or I am not doing it right.
