Without knowing what did you actually benchmark, the numbers are 
prettymuch useless.

If you measured how long does it take before the parser waddles 
through the file with the default settings, then it might mean 
something for the libraries that just produce some in-memory 
representation of the file, but comparing that to the time it takes 
for the event based parsers to generate all the events and ignore 
them is pointless.

What was the task?
