# did you provide enough heap to the JVM process too? -> -Xmx3G -Xms3G # Did you configure batch.properties to reflect your target store file sizes ? (# of nodes x 14bytes for nodes and # of rels x 33 bytes for relationships) ? -> the total amount for all stores should be total heap - 500MB -> otherwise it will swap out to disk which you def. don't want # 4GB might be a little to small in terms of RAM if there is also other stuff running # make sure your disk is fast enough and configured correctly: http://structr.org/blog/neo4j-performance-on-ext4
