Taking too much time for exporting to pod

Hi,

I am using Blender 2.65a. I am trying to export a human model, which has lot of lipsync and the size is around 45mb. When exporting to pod format to use it further in Cocos3d iOS app, it is taking around 20 mins to export. What could be the reason for this delay? How do i make it export performance well and quick? I am using Macbook Pro. Please advise!
