XML vs. JSON

The website project that I'm currently on heavily uses your dhtmlX controls. We primarily utilize XML as the format for data to load controls. However, at times it is somewhat slow. Someone informed me that your controls parse JSON faster than XML. I was wondering if this is true? If so, could you add this to your documentation for future reference?

Loading data from JSON may be only about 5-10% faster than XML.

There is Smart XML Parsing in tree and Smart Rendering in grid functionalities that allow to improve performace in sevaral times.
