Tilman Hausherr closed PDFBOX-2908.
-----------------------------------
    Resolution: Won't Fix

We're only fixing small bugs in the 1.8.* version, not making optimizations. The 2.0 does have some possible improvements related to streams and temporary files. Hint: in the 1.8 versions, if possible, always try to read from a file and not from a FileInputStream.

> I inserted raw time reporting functions before and after PDFTextStripper.writeText, it looks like it takes quite long to writeText to a StringWriter (84045ms for a ~1M pdf file).
> It looks like a 1.8.x issues (I can reproduce on 1.8.9 and 1.8.10, didn't test on other versions yet). When I switched to 2.0.0-SNAPSHOT, and the time improved dramatically to 532ms using the same code and for the same pdf file. What I changed in code was only one import to accommodate PDFTextStripper's package change in 2.0.0.
