<BODY>
<P><FONT SIZE=2>I have perhaps not used the most scientific way. I comment out the code that builds the document and checks how big the program becomes. Then I uncomment the lines that builds the document and then checks the size again. I then take the second value and subtract with the first value. Very simple. The "program" is a RMI object and the only thing that happens before the document parsing is that I bind the RMI object to the registry. The program takes about 40Mb without the document and about 150Mb with the document (which tells me that I have to revise what I said earlier, the document is "only" about 110Mb big in memory).</FONT></P>
