How to speed up the generating of PDF

[Alvin Tan <al...@patroids.com>]

Hi,

I need advice or help in speeding up the process of generate PDF. I have 26
xml files and each has its own xsl file. In my program I generate 26 FO
files using the xml and its xsl. After that I generate 26 PDF files and then
merge all 26 PDF files into one PDF file. This process takes me about 5
minutes if there are low resolution image in every PDF file and about 9
minutes if I'm using high resolution image. Any way I can speed up the
process? Any help is greatly appreciated. Thank you.


Regards,
Alvin

You can also use XalanCommandLine as described in the docs 
which calls first Xalan and then Fop.

Yes. Write a small Java app which invokes Xalan and redirect its output
as SAX or DOM directly to FOP. Then the FO data doesn't have to be
serialized and written to disk.

This is how I generate the FO:
java org.apache.xalan.xslt.Process -IN file1.xml -XSL file1.xsl -OUT
file1.fo

And this is how I generate the PDF:
java org.apache.fop.apps.CommandLine file1.fo file1.pdf

Is there any better way?

Do you write the FO data into a file which is then read (and parsed) by
FOP? It might be faster if you let the XSLT processor send its output
directly to FOP using SAX or DOM.
