Material Param Tracks super slow!

Xoliul

So I've got a few material param tracks in Matinee. some of them control materials that are on just one or two objects, others are for materials on dozens, maybe even up to a hundred objects. Turns out that performance of the editor goes out of the window as soon as I make a track for one of these frequently used materials. Updating things can take minutes, even closing the Matinee editor takes more than a minute.
This is seriously killing my workflow, anybody have any advice (Jordan)?
