Hello, We are upgrading our SAP Java Application servers to use SAP JVM 8.1 Patch Collection 39. This release integrates updates from Oracle JDK 8u172
The GC shall be switched from -XX:+UseConcMarkSweepGC to -XX:+UseG1GC. On the following website:- https://docs.oracle.com/javase/8/docs/technotes/guides/vm/performance-enhancements-7.html#numa There is a note on NUMA Collector Enhancements for the Parallel Scavenger garbage collector. Are the subsequent collectors, namely the G1 garbage collector also NUMA aware? Is it default? May I use the -XX:+UseNUMA flag with -XX:+UseG1GC?
