-------------------------------------------------------------
The slowness is due to the lack of inter-page resource caching in 2.0. We
re-load all resources for each page which is slow for this file because of the
"post" table in the embedded fonts, which takes a long time to parse. I have a
patch which adds back caching (via a new interface) in a flexible manner, see
PDFBOX-2370. With my patch this file goes from 22sec to 8sec on my box.
