JC,

I am not an expert on Iostreams, but I was able to obtain a significant 
performance improvement by removing temporaries and passing by reference 
instead of by value.  I have attached the code.  Notice, that I am using 
back_inserter and make_iterator_range instead of stringstream operations.

Hope This Helps,
Justin
