Hi ,

Would like to know the best JVM settings for Elastic. As per Elastic 32GB max RAM and enabling memory lock and disable swapping is mentioned for tuning.

Do we need to consider any other parameters for Elastic JVM tuning like GC settings (HeapDumpOnOutOfMemoryError, ParallelRefProcEnabled, ParallelGCThreads)?

Thanks!
