> Performance problem in class COSWriter:
> Constructor of COSWriter takes 2 args:
>         COSWriter(OutputStream os, FileInputStream is)
> method saveIncremental in class PDDocument:
>         saveIncremental(FileInputStream input, OutputStream output)
> It create COSWriter with this args. If I pass FileInputStream into saveIncremental then signing the document goes quite a long time.
> If you pass BufferedInputStream, the signing speed is increases. But alas, this is not possible, because the parameters of the method saveIncremental does not allow to do this.
