Anton, to load big datasets, you normally will want to use the Neo4j Batch Inserter, http://wiki.neo4j.org/content/Batch_Insert . However, we have not put it under the RDF components, meaning that you through the SAIL/RDF interface only can use the full Neo4j kernel, resulting in "normal" instertion speeds. Try setting up the JVM heap and the transaction size, so you get best speed out of it. Let us know if you have problems!
We are planning to change that and make fast RDF insertions possible, but have not come around to doing that. Of course, if you look at http://components.neo4j.org/neo4j-rdf/, you can yourself create a similar structure via the raw batchinserter, but I guess it is some work to get it working.
