Just run pretty much any query over more than toy data, say 1 - 100 MB 
instead of 1 KB.
For example, simply run a benchmark driver such as

java -server nux.xom.tests.XQueryBenchmark 1000 3 xom 
samples/data/randj.xml samples/xpath/queries1.xml

The only reason I didn't publish the results for XOM's Jaxen XPath is 
because I considered them too embarrassing for you. It really escapes 
me why you are asking for it. Shall I really attach the catastrophic 
numbers to this mail?
