Wiggle effect is slowing down computer and multiplying render time

Does anyone else have this issue:

Adobe recently added new effects to Premiere Pro, including the “Wiggle” effect which is pretty handy when trying to make anything look like it’s floating.

The big issue is that as soon as you have more than 10 instances of the Wiggle effect in your session

• it slows down the session
• timeline manipulation becomes laggy and almost impossible to work with unless you turn down the Playback Resolution to ¼ or more
• MOST OF ALL: Renders explode, taking up to 3hrs instead of a couple minutes !! 
   

The attached screen shot is from a session where I have a total of 40 instances of the effect.
The example image has 4 instances, and there are multiple of those shots in the session.

 I’m not a developper but I’m wondering how a “simple” transformation effect can have such a huge impact on processing and render time.
Maybe I should just do this kind of work in AE entirely?
