[jira] Created: (MPXDOC-120) Faster execution of xdoc:jelly-transform with ant:parallel

Message:

  A new issue has been created in JIRA.

---------------------------------------------------------------------
View the issue:
  http://jira.codehaus.org/browse/MPXDOC-120

Here is an overview of the issue:
---------------------------------------------------------------------
        Key: MPXDOC-120
    Summary: Faster execution of xdoc:jelly-transform with ant:parallel
       Type: Improvement

     Status: Open
   Priority: Major

 Original Estimate: Unknown
 Time Spent: Unknown
  Remaining: Unknown

    Project: maven-xdoc-plugin

   Assignee: Arnaud HERITIER
   Reporter: Matthias Kerkhoff

    Created: Tue, 14 Sep 2004 6:07 AM
    Updated: Tue, 14 Sep 2004 6:07 AM

Description:
In larger projects or in multiproject builds transforming the xdoc files into html may take a significant amount of time.
After looking into the plugin.jelly - especially into the definition of the doc:performJsl tag - I would think that there is an opportunity to distribute the transformation workload over multiple threads/cpus. 
The best candidate for doing so would be the for-each loop over docFiles (lines 328-367). It should possible to reduce the overall transformation time with the ant:parallel task.
The effect should be noticeable on multiprocessor build machines and/or builds which transform many xdoc files, as they may for example occur in conjunction with the statcvs-plugin.

It seems a good idea but what is the difference between ant:parallel and jelly:thread ?

Rather than Ant's parallel task, why not use Jelly's thread tag?

I suggested ant:parallel because its threadsPerProcessor attribute. I'm not sure how to model a similar behaviour with the jelly:threads taglib.
