The other common problem is long page sequences, if you can break your document into multiple page sequences of about 10 to 20 pages, there is quite a significant performance improvement

Is there something similar you can do in a servlet?

It works fine until the size of the pdf become bigger then 20 pages (I have to process files of 200-300 pages). Then the servlet will stop when I render the document doc: driver.render( doc ); and after some time I get 'page can not be displayed' or java.lang.OutOfMemoryError (I got 512MB RAM). Can somebody tell me how to render big documents on the server. Jens
