The direct comparisons were with the DOM parsers (I was playing with a D 
port of some C++ code at work at the time, and that is DOM based).

xmlp has alternate parsers (event driven etc) which were faster in some 
simple tests i did, but I don't recall if I did a direct comparison with 
Tango there.
