Config optimization for heavy query traffic

is this a continuation of https://community.neo4j.com/t/query-optimization-that-collects-and-orders-nodes-on-very-large-graph ???

Regardless I'm curious how you came about

NEO4J_dbms_memory_pagecache_size=32G
NEO4J_dbms_memory_heap_max__size=32G

How large is your graph on disk? and how much total RAM is on the instance?
