Should we rewrite the XSL in CDuce?
We currently have a huge XSLT transformation that takes 20-30 minutes to process. We need to improve the performance and we are considering CDuce. CDuce looks promising. What is a good approach to doing this? Do we have to rewrite the entire xsl logic in CDuce?
You could rewrite it in another language but there may be easier options, it depends how efficient that XSLT 1 code is. If it uses // a lot then it is not uncommon to get orders of magnitude speed improvement by rewriting it not to use // and to use keys or other constructs instead. Also of course switching to a newer more highly optimised XSLT engine wouldn't hurt. (Your question is tagged xslt 1 but an XSLT2 engine would be able to run it with no or little change)
