Because of some reasons, our team try to use our own format to storage diagram, instead of default format which you guys developed. Our format probably is like below:
<OurDiagram>
   <Nodes>
        <Node Caption="aaa" Width="300" Height="100" ...>
       ...
   </Nodes>
</OurDiagram>

So we need to load xml file first then get all and every node data to create node shape and append it to a diagram dynamically.  My question is on one same diagram maybe there are more than 10 thousand shapes. The loading performance is as same as the way which using default format file to load a diagram?

Thanks
