Command Line |
-XX:-UsePerfData -Xnoclassgc -XX:+UseParallelGC -XX:+UseLargePages -XX:+AlwaysPreTouch -XX:-UseAdaptiveSizePolicy -XX:MaxTenuringThreshold=15 -server -XX:TargetSurvivorRatio=90 -XX:SurvivorRatio=34 -XX:LargePageSizeInBytes=2m -Xms225g -Xmx225g -Xmn220g -XX:ParallelGCThreads=64 -XX:InitialCodeCacheSize=25m -XX:InlineSmallCode=11k

Tuning |
Used numactl to affinitize each Backend JVM to a NUMA node, eg: - Group 1: numactl --cpunodebind=0 --localalloc
- Group 2: numactl --cpunodebind=1 --localalloc
- Group 3: numactl --cpunodebind=2 --localalloc
- Group 4: numactl --cpunodebind=3 --localalloc
