Neo4j is written to be fast for 1) many concurrent reads and 2) smaller concurrent transactional updates which is the common use case for most applications. Try to group more operations in a single transaction to get higher injection speed. This is typically only a problem during testing (I need to load all this data to test something) and not in production when data growth will be more suited for smaller transactional updates. Maybe the batch inserter can help you here.
