It sounds like you're complaining that the JVM sometimes does stop-the-world GC.

You can mitigate this but not (for most workloads) eliminate it with
GC option tuning.  That's simply the state of the art for Java garbage
collection right now.

Hm, but what to do in this cases?? In these moments throughput of cluster degrade, and I misunderstand what workaround I must do to prevent this situations?
