jackrabbit is not optimized for very flat node hierarchies (e.g. with more than
30k child nodes per node). if you create a deeper structure you'll experience a
lot better performance.

anyway, your figures seem to be *very* high (200s for 1k nodes)...
are you using any of the foillowing?
- references
- versioning
- large binaries
