Hi,

There are unfortunately very few published performance 
guidelines. The best overview is probably in the FAQ at 
http://www.dpawson.co.uk/xsl/sect4/N9883.html. 

I think it is fairly well understood that all others things being 
equal using for-each will be quicker than template matching. The 
caveat is that the improvement is often so small as not to be 
important and template solutions are normally much cleaner. In 
this particular case (with simplified stylesheets) I measured a 
4% difference for a file with 2000 entries in favour of using 
for-each. As the document size grows so does the difference. 
This was on the Sarvega processor, other processors may be 
different.

Kev.
