Hi, I'm using Neo 3.0.2 community edition and running the import tool I just found that on a machine with 4 cores and 32GB of RAM the import is actually ~2x faster than on another (virtual) machine with 38 cores and ~60GB of RAM.
With 4 cores and 32GB: Available memory: Free machine memory: 16.88 GB Max heap memory : 6.97 GB ... ... IMPORT DONE in 1m 32s 624ms. Imported: 4135534 nodes 43160516 relationships 51504726 properties With 38 cores and ~60 GB Available memory: Free machine memory: 24.08 GB Max heap memory : 13.14 GB ... ... IMPORT DONE in 2m 45s 299ms. Imported: 4135534 nodes 43160516 relationships 51504726 properties Is this the expected behavior? I found in [1] that the community edition scales up to 4 cores (it says for version 2.3 but I assume the same holds for 3.0) but with more cores I'd expected at least a similar performance, not 2x slower. Should I use a machine with maximum 4 cores? Or can I configure Neo4j somehow to avoid such a decrease in performance? Also, is there any constraint about available memory and how the community edition scales or more memory should lead to better performance?
