Well, if you can make the document public, you can always create a bug 
report in the Xalan-C bug system, and someone will take a look at the 
performance issue.  It's possible we could fix it in the next release, or 
even provide a patch for a current release.

By the way, I'm not sure how you can report that Xalan-C is 4-5 times 
slower than xsltproc for the 17MB file when you killed the process after 5 
minutes!  That doesn't make any sense at all. Can you elaborate more?
