I put it under Tutorials/Performance.
this sounds great :-) Did you do this for 1.2 or 1.4?
Would it make sense to apply this as a patch or does it leave some other
functionality out?
Cheers

Note that I left the sitetree.xml concept, did some tests and even
with 100 000 docs response times were acceptable (which is all I
need).
Any comments are welcome !
bye,

At one stage I attempted to get my EJB backend to use a relational
model to render the sitetree. It didn't work very well, my biggest
problem was trying to delete a node from the tree. As the UnitOfWork
is the only thing which ultimately writes to the database, I had to
make each SiteTreeNode implement transactionable.
The other problem I found, was that requests for sitetree.xml just ask
for the contents of the entire file. My ejb sitetree had to output
that xml, I tried various methods of caching that but it turned out to
be very inefficient.
I'm now just storing the sitetree in xml format the same as the normal
lenya repository. If anyone has some suggestions of how to change the
cocoon pipelines which handle requests for the sitetree, so that it
can request a subset of the tree, I'd be interested in trying to
implement that.
