Subject Re: Performance Comparison

I think it goes deeper than that. When I checked just the time spent in 
the Rampart/WSS4J code it didn't account for all the overhead. It looks 
to me like there are some stream to String or stream to OM conversions 
going on even outside of the Rampart handlers.
