Whenever generating PDFs in bulk, we usually don't change a lot of the structure of the html and a the css is intact between executions.

It would be nice to have a feature where we could initialize Prince once, and it would load up some things into memory to make every subsequent execution faster since things are preloaded. It could help save on execution time and memory footprint.

What do you guys think?

How long is document conversion taking currently? Are the generated PDFs very large, do they contain complex tables or refer to remote network resources?
