Hi Stepan
What costs most in your setup is actually the JVM startup (including
class loading and just-in-time compiling), and that for each document.
No, FOP cannot split anything from the command-line.
You could try FOP's Ant task [1] to solve your problem if you're no Java
programmer. Ant [2] allows to parallelize [3] tasks and with the FOP
integration this should allow you to run just a single JVM for all
documents. You could even do the XSLT in Ant, i.e. your whole process.

Hallo!
I am looking for the fastest way to create 100.000 unique PDFs. I have
10 unique XML files per 25 MB (result of output from SQL database),
each one contains data for unique 10.000 letters. I have to create 100.000
letters in PDF per 1 or 2 pages. Now I am doing it in following way:
1) For each of 10 XML file do XSL-T 2.0 using Saxon 9.2, which produces
100.000 FO files per 4 to 7 kB. Technically I am doing it by 10 times
call of XSL-T using Saxon, which split input using xsl:result-document
2.0 instruction. This is fast enough for me, it takes about 18 minutes.
2) Now the painfull process. For each of 100.000 FO file do FO to PDF
using Apache FOP 0.95, which produce 100.000 PDF files per few kB.
Technically I am doing it by 100.000 times call of FO to PDF using
Apache FOP. I guess, that the problem is time for starting and closing
Apache FOP from command line. Is there any other efficient way, how to
do it? Like to specify not input exact file, but wildcarded filename.
Of have I do some Java programming with Apache FOP? Or can Apache FOP do
some kind of splitting output?
I tried to solve it by parallel transformation using
for %%f in (*0.fo) do fop...
for %%f in (*1.fo) do fop...
for %%f in (*2.fo) do fop...
...
in separate batches.
because my files is named sequentionNumber.fo to be able to utilize
more cores, but it should have the right effect on 10+ cores computers.
Utilisation of cores is 100 %, RAM is OK.
I am using Sun Java 1.6.0_05 on MS Windows Vista 32bit Enterprise,
Intel Core2 6600 at 2.4 GHz, 2.0 GB RAM, java -Xmx=128m.
Thank You for help in advance. Stepan
