Then I'd assume it's the query that takes a long time to execute.

You can try the following configuration tweaks:

- disable document order on the query result
   See: http://issues.apache.org/jira/browse/JCR-145
- set the paramter 'resultFetchSize' to a lower value if
   you don't need all 2000 nodes, but are only interested
   in the first few. please note however, that there are
   security concerns with this option:

on unix:

kill -QUIT <java-process-id>

on windows:

Ctrl-Break in the console where you started the java process

The thread dump is sent to the standard out of the java process.
