Pixmaps are in system memory and can be manipulated directly, so they can't be drawn without boshing them across the AGP pipe to the videocard first. Hence the slowdown you referred to.
Images are in video memory, and cannot be manipulated directly. Drawing them has no additional cost because they're already in video memory where the card needs them to draw them.
It's horses for courses. If you want to manipulate images, you have to use pixmaps because they're the only option. If you don't, it would pointless to have an overhead you don't need.
