---------------------------------------

Did you some micro-benchmarks with an appropriate file? Can you share where the bottleneck is? Did you check it with VisualVM or alike?

> We're using JXPath to parse some input from a client. When they give us a valid date it gets transformed from a SOAP message into Java objects. When this happens JXPath queries suddenly take 1-8 seconds more (depending on system -- the optimized system it's 1 second, dev & test machines it's 8).
> Kicker is, we don't even look for this field. Just its existence does it.
> (we've quickfixed to omit the xml tags before the string is parsed into Java for now)
