Are you talking about Poser 5 - Firefly, Poser 5 - Poser 4 Render, or Poser 4 Render? Kind of makes a difference. With Poser 5 - Firefly, it usually takes me a few minutes (2-5) to render a scene, but I don't have much complexity to my graphics, and I'm not trying to do animation. What bogs me down is dynamic hair and multiple lights with shadow maps (I often render drafts without shadows for that reason), and rendering to a new window (staying in the same window for drafts always seems faster to me). I'm sure everyone will have a different story to tell, and probably more expertise to share.
