I've had some experience with PDF::API2 and formatting images. The PDF::API2 code rips apart the source image, decompressing it pixel by pixel, then scales and reformats it into the appropriate PDF image content using nothing more than pure Perl. It's a slow process, sometimes painfully slow. I thought I was being smart working with large high resolution image sources, to preserve the quality of the final PDF, but that just brought the render process to it's knees.

The most effective thing you can do to speed up render is reduce the size/quality of your source images in a graphic editor first. Reduce it to the smallest image size you think you can use without sacrificing the final result. This will make a huge difference. Any images you can generate in advance and include as a pre-generated background (take out of the loop) would also be a good idea.
