Let's say some people that I get my money from did not want to take the 
risk to use functionallity that is not in the specs and thus might be 
not available in other parsers. Well, they convinced my at last.

Actually it's not a libxslt but a libxml2 issue, so you want to move it 

Using libxml2 2.5.10 (Igor's win binaries) I get the following times for 
  the serialization of a 7.7 MB xml-file:

xmlSaveFormatFileEnc      : 2.1 s
xmlDocDumpFormatMemoryEnc : 77.2 s

I don't know if you still confirm that this is an unexpected behaviour. 
Should I still report it to bugzilla?
