The numbers for a Java (not Javascript) extension called from a Java based XSLT processor are likely to be different. I agree though that for the majority of stylesheets the difference between using an extension and a ready written XSLT library such as FXSL is not worth bothering about for performance reasons. There might be implications with regard to testing and validation though.
