Hi, I already tried these java parameters, but that didn't really speedup the process and i already turned atime off. As Java parameters I am using right now -d64 -server -Xms7G -Xmx14G -XX:+UseParallelGC -XX:+UseNUMA What I've also noticed is, that reading from the database is really slow on my hard disk. It just reads 1mb/s and sometimes 8mb/s, but that is really slow. My hard disk can normally read and copy files much faster. Also very strange is, that the workload of the hard disk is around 99% with reading 1mb/s.
My OS is Ubuntu Linux x64 and my file system is ext4. On the neo4j Wiki I found some performance guides, but these didn't really help. Do you know what I can do else? Perfomance Guides: http://wiki.neo4j.org/content/Linux_Performance_Guide http://wiki.neo4j.org/content/Linux_Performance_Guide http://wiki.neo4j.org/content/Configuration_Settings http://wiki.neo4j.org/content/Configuration_Settings I also added a configurtion file, but it seems that my Java program doesn't use all of the Ram. Thanks for your help!
