Andreas Lehmkühler commented on PDFBOX-136:
-------------------------------------------
As fas as I understand mig-o made the experience that the writing performance
of pdfbox depends on the used outputstream-class. And I guess that everyone
agrees to that fact. But the suggested solution isn't appropriate. The class
COSStandardOutputStream and at least the class COSWriter are using the abstract
class java.io.OutputStream as type for the stream the data will be written to
give the user the chance to choose his favorite kind of OutputStream. instead
of changing the pdfbox code, the user has to create the preferred kind of
outputstream and has to pass it to pdfbox.

> by
> public COSStandardOutputStream(OutputStream out)
> {
> super( new BufferedOutputStream(out,16384) );

> . Here are some timings for my local drive (i do some
> other stuff for the first 4 seconds...).
> old way: 5103 ms
> new way: 4403 ms
> On my remote drive:
> old way: 136792 ms
> new way: 4756 ms
> The reason should be clear... Network-packages for
> nearly each and every written byte in the pdf.

> The bug is, that only the old way exists in the repository,
> so i wrote this, to have someone change this in cvs.
> Or does anyone has cvs write access here? Then the bug is my
> stupidity, since i could have it done myself :)
