Is there any difference in performance between session.getRootNode()
and session.getNode("/")?

Hmm, this is weird.
If I use session.getNode("/path/to/some/node"); at start, it works
in 2 seconds
If I use session.getNode("/"); it takes 25 seconds...
Under /, there is only two nodes (jcr:system) and my application
root node.
Once found, I get the root in 0ms, but maybe it is cached.

Rakesh,
Each time I create a connection and get the root node.
After that, each access to a node seems a little slow, so querying
and fetching the 1500 nodes described below take one or two
minutes, but maybe decreasing the number of nodes could help. But
here, nothing as dramatic as 27 seconds for one node.

Thanks Rakesh for your reply,
actually root have only one node, below 2 or 3 levels of that of
that there is one node with 1500 nodes, this is the maximum. All
other nodes have between 0 and 10 nodes.
1500 may be a lot and I may implements a tree strategy to
decrease the number of child of this node. But does that sub-sub-
sub-sub-node make the getRootNode() going that slow?
No, that should not affect the root node retrieval. Is the time
to access repeatable, or just the first time?

I have inserted ~25K nodes with ~1500 files (about 1.6G of
files) and now Jackrabbit takes 27 seconds to get the root
node, is it normal? Maybe it is because am I using the
standalone server (2.0)? Also I am making tests since jcr2spi.
I'm a newbie with JackRabbit configuration files, so I did not
make much modifications to repository.xml
In my experience the biggest issue is the number of child nodes
under a parent (and not repository configuration). The general
recommendation is to try and keep child nodes low (1000 does not
seem too bad in my experience), but not 25K under a single parent.
