Hi Alican, > But I am still a bit concerned about the 128GB RAM..
You can run it on less of course. You could run it on your laptop and it would still work. However Neo4j is clever in its use of RAM. The more RAM you can allocate to Neo4j, the more chance that database reads can come straight from memory rather than spending potentially milliseconds going to mechanical disk, yielding thousands of traversals per second rather than millions. So more RAM = less disk hits (statistically) which is where you'll get huge read performance benefits. Less RAM means more likelihood of going to disk. All things being equal, with 128GB RAM you can cache a lot of your dataset in main memory. Perhaps even all your *active* dataset in fact (since it's about a quarter the size of your full dataset). That's going to give you blistering performance. Jim _______________________________________________ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
