- How can you be so sure?


One of my test-transformations applied on a huge dataset takes between 1
and minutes. In cocoon 2.0.3, I can see that the output is delivered
immediately, in 2.1 the output starts to appear on the screen after 1-2
minutes. 
The pipeline is

      <map:match pattern="renderhierarchicalfiletoc_xalan.xml">
        <map:generate src="Testfiles/hierarchicalTOC.xml"/>
        <map:transform type="xalan"
src="stylesheets/toc_fromhierarchicaltoc2.xsl"/>
        <map:serialize encoding="UTF-8" type="html"/>
      </map:match>

There is no sorting in the transformation which could prevent it from
streaming.
