How about Tamino speed test?

Who can do a Tamino speed testing and give us the
When document beyond 100M, XQuery is very slow.
But I want use Tamino to manage a large xml document about 500M .
Maybe it is a silly idea?

Tamino works very well with large numbers of small documents, but performance is less good when handling very large documents. This is because of the granularity of the indexes: indexing helps to identify the document you need, but it is less effective at finding data within the document. You should therefore try to find ways of splitting a very large document into lots of small ones before storing the data in Tamino.
