Hi Michel,

Most probably the problem is on the various XPath expressions and/or loops (for-each) existing into the XSL file. I have great interest for XSL performance issues, but I am not able to give you more specific tips in order to improve the performance of this specific transformation. Having said that, I would be very glad if you could send me a sample of the XML document you are using directly to my e-mail (fmvazque@terra.com.br).

If there is any confidentiality issues involved, you could replace the real data with any bogus information. That doesn't matter that much in this case.

Thanks!
