So you suggest that storing data as attributes could be more efficient in Jackrabbit? After weekend I'll try to provide some results of the same test cases but with another set of XML-s with storing based on attributes, I'll also make some comparison charts.

If there are any give me some suggestions how data should be organized to fit best in Jackrabbit architecture - what should I avoid, where are the limitations/depth, number of subtags on one level, etc./ ?

Hi,

I can't share those files but I can give you some stats:

Your data set seems to primarily use tags instead of attributes for
storing content. Jackrabbit nodes are quite a bit "heavier" than DOM
nodes, which probably explains the difference in performance.

As a rule of thumb I've sometimes used a rough metric that a
Jackrabbit node is about an order of magnitude more expensive than a
DOM node. I think we probably could improve this quite a bit.
