Comment on Neo4j Performance Revisited and Appreciated by Peter Neubauer

Nice write-up!
To avoid GC hits during read operations, try to play with the memory settings listed under http://wiki.neo4j.org/content/Configuration_Settings#Optimizing_for_traversals_example which might help?

Comment on Network versus Relational by Anders Nawroth

I think the difference between the implementations is that Neo4j actually traverses all the way down into the file system hierarchy, while the Derby solution does not. The data has a network/hierarchical structure, but the query doesn’t! To remedy this, you could simply add one more constraint: only look at files inside a specific directory (and its subdirectories) inside the file system.

You might use @Grab in your Groovy code to directly include the dependency to the Neo4j jars. When doing this, you no longer need to struggle with your classpath.

Of course, I should also mention that the shell supports running Groovy scripts:

Coolio! Btw, one way to check what’s in the database is to fire up the Neo4j shell:

You might also want to look at vtd-xml, the next generation XML processing model that is far more powerful than DOM and SAX http://vtd-xml.sf.net
