Thank you, Jeremias, the test run fine.


I have a small file.xml and a file xml2fo.xsl to do the transformation xml
--> fo via xsl.

When I test this file file.xml with the FOPBenchmark, 
I obtain a duration of 0,39 seconds! in the results.xml (with the variant
"from-it") :

  <scenario name="xml2fo" variant="from-if">
    <description>Apache FOP: preModel.xml example, rendering from
Intermediate
      Format</description>
    <environment>   
      <value name="java.specification.version">1.6</value>      
    </environment>
    <run idx="0">
      <run>
        <value name="target-format">PDF</value>
        <page-count>2</page-count>
        <duration>390</duration>
        <file mime="application/pdf;mode=painter"
size="24294">file:/C:/Users/greg/workspace/FOPBenchmarks/benchmarks/dev/05/file.if.pdf.if.if.pdf
        </file>
      </run>
    </run>
  </scenario>


So when I take my file.if.xml in my Main class java to do my transformation
if --> pdf.

I can obtain a file.if.pdf (2 pages), also the transformation take 2.4
seconds ! I think it's very a long duration when I see
<duration>390</duration> in my results.xml ! 

Do know why then I use a class java the duration is very long ? 
What can I do for obtain a more small duration ?

Thank you.
