I am running Neo4J Enterprise on a box with 264GB of ram. there is nothing else running on the box. We are still trying to figure out the best settings for rapid search of a growing dabatase (35 million nodes, 150 million relationship and growing).
If I set the heap size to anything larger than 200GB Neo fails to start because the relationship and node cache array tries to configure an size that is larger than the largest allowed Java array. I tried explicitly setting those to a setting like .8 but the config won’t allow a size smaller than 1, hence the limit of a 200GB heap. My other memory settings are indicated below: node store mapped memory = 3G relationship mapped memor = 15GB propertystore mapped memory = 15G string and arrays mapped memory = 230M each node cache = 25G relationship cache = 30G I’m clearly looking to optimize query and graph traversal speed and willing to cache as much as possible in memory. We so a lot of faceted searches with counts. If you can recommend better settings I would be much obliged. -------------------- Clark Richey, CTO FactGem 240-252-7507<tel://240-252-7507> [email protected]<mailto:[email protected]> [cid:B01C1377-ED24-4820-A659-3280B84C974A] Need immediate assistance?
