How to increase the usage of RAM

Dear all, the following is my RAM information in task manager when I'm query for about 1000 million nodes.

However, whenever I tried 1000 million, 5000 million, 10,000 million or event 50,000 million node, the usage of my RAM are all about 12% (62/515) with 88% free left. How can I increase the usage of my RAM as larger as possible so it would be more efficiency? Thanks.

The following is my detail of Neo4j.conf

It's been a long time since I looked at how Windows reports memory usage... Are you getting acceptable performance?

Hello @Peter_Lian :slightly_smiling_face:

You should execute the command neo4j-admin memrec (Neo4j 4.4) or neo4j-admin server memory-recommendation (Neo4j 5) to get an initial recommendation on how to configure memory parameters for Neo4j.

I had already set the initial_size, max_size and pagecache to the value what neo4j-admin server memory-recommendation showed and even try different value before, but the RAM still all about 12% (62/515) with 88% free left.

Based on the evidence, it seems like Task Manager just doesn't do a good job reporting memory use. If you're getting good performance, don't see evidence of swapping -> win :slightly_smiling_face:

Yes, all I want is just to improve the performance as much as I can.
