Hi everyone,

Here is a small question about Modeshape's performance.

My team leader would like to improve the speed of our methods that get back (only reading) data from JCR. The basic operation is to get a part of the JCR tree with a given depth.

First here is our score: 8.2 seconds to get 1370 nodes containing more or less content on properties, from the root with a depth of 10 levels.

The amount of data loaded doesn't exceed 200KB.

Here are the specs of my dev workstation (on which i runned my test) if it could give some relevant figures:

Software figures:

JBoss 5.1 AS (default configuration)

JDK 1.6.0_23

Hardware figures:

Intel Core i5 2x 2.67GHz

4Go RAM

The whole thing running on Windows 7 Pro 64Bits.

I don't know if this score is likely to be expected on such a computer, i have no idea at all right now, except that it looks quite long for only 200KB max.

The methods that reach JCR content via Modeshape were done before i came in the project team, and maybe (certainly) we could improve the way we reach data though Modeshape.

I just browse a little bit the JCR 2.0 Specs and the Modeshape guide, but didn't really find something that points me out the best way to get a part of the JCR tree, so here is my question.

How should we proceed to get a part of the tree? (We want all the tree structured in one browsable object, until now, we're using an Element from Jdom to store our graph.)

Basically, here is how it's performed:

(Element class being from org.jdom, Node class being from javax.jcr)

public Element get(Node n){

     Element e = node2Element(n);

     for(Node c : n.getNodes()){

          e.addContent(get(c));

     }

     return e;

}

So you can see that we're browsing the tree, branch by branch, deeper and deeper. Is that the fastest/proper way to go?

If by any chance, you've any idea on that matter!

Thank you very much by advance,

SJ.
