50 seconds to get the text from a 200-page PDF seems slow to me, based just on intuition, rather than measurement. It suggests that there may be some inefficiency in the code—I would at least check for that before determining that the speed is the best possible.
Considering that I can render a 200-page document from XML source to PDF in a minute or two using XSL-FO and complex XSLT processing, which is pretty data processing intensive, it doesn’t seem like just extracting the text from the PDF should take a comparable amount of time, although there is some data processing involved there as well, of course (for example, decoding all the encoded strings). It would be useful to see if different Acrobat-provided PDF optimizations make a difference, like making the PDF streaming enabled or turning off compression.
