Saving Projects with Warp Stabilized Footage takes Forever

Hi,

1)

I have 8 comps in my project all enjoying the wonderful stabilization of Warp Stabilizer.

When I save the project - it takes 10 minutes. Removing all the Warp Stabilizers from the footage it takes 1 second.

2)

Having done all my work in the 8 comps all having Warpy applied to them then dragging the comps over to Adobe Media Encoder for rendering takes about 20 minutes.

Removing Warp Stabilizer from the Comps and repeating above takes 1 minute.

I think that warp stabilizer is great but then workflow slowness hit is devastating.

Is all this normal behavior ?

Thanks
