Daniel Persson commented on PDFBOX-6008:
----------------------------------------
Hi Tilman
Thank you for quick resolution. The improvements are awesome. Ran it locally
with our tooling and the file could be run in a second or two. Also ran through
our full test set of 50k+ pages with out tooling and could not find any
regressions. This seems like a great improvement and really looking forward to
the next release. Currently we see one of these files at most one time a month
but it has a big impact and grinds the process to an halt.
Best regards
Daniel
