-Xnuma:none

(AIX®, Linux®, and Windows™ only)

Use this option to turn off non-uniform memory architecture (NUMA) awareness when using the balanced garbage collection policy.

For workloads that do most of their work in one thread, or workloads that maintain a full heap, turning off NUMA awareness can improve performance.

Syntax
