That sounds suspicious. Parsing has a lot more overhead than just 
writing out text strings. I suspect the real comparison here may be 
between a system that does full well-formedness checking and one that 
doesn't. Many systems can blast XML out pretty quickly using printf or 
equivalent. They don't necessarily need to call a method for each tag or 
text node or check well-formedness on output.
