Is there any easy way to check for compatibility issues, missing or corrupt text, malformed pages, and/or speed?
My experience is that the most common type of "slow" PDF is when the PDF uses a highly-compressed bitmap compression format such as JPX. A lot of archived books use this. Using k2pdfopt with the -i option will show you the internals of the PDF. Do you have a couple examples of the slow ones?
