Hi Lucky, It is a bad practice to set JVM memory >= 32GB. Usually, you can get a performance degradation for heap > 10Gb due to heavy GC. Also it make no sense to have different Xms and Xmx params on server side as, JVM never revert back free memory to OS.
>From ignite-2.x there is no need to have huge heap as all your data will always resides in off heap. For 1.x versions, you can add more nodes with smaller heap or use OffHeap memory mode. See recommended settings [1].
