Motion Capture Animation frame issue

So i was gonna motion capture my character in blender, i imported my character to blender and then imported the .bvh motion capture file to the same project.

When i had both my motion capture and my character in the scene i got about 60fps when i was running the animation.
But when i attached my character to the motion capture i got like 0.02 frames/s, even as i deattached my character from the motion capture it still runned like 0.02 frames…? why is this happening?

Blenderartists doesnt let me attach my .blend file here so i cant attach it right now.

Here is the blend file : http://www.mediafire.com/download/28d2238qsei4arj/Allods_--.blend

I made a new scene and i try to compare it with the old one, and i try to understand what it was.

From what i understood its something with the BVH and sapling tree animation? as long as i have 1 of them its okay, but when i have both in the same scene, i get an extreme low framerate? not sure why but its fixed now.
