And if you do any IO with bytebuffers or library that does that -> you simply gonna have a bad time with native memory usage which is 10x as convoluted as selecting GC and carring only about the heap.
And best part, every month there is a new bug released in regards to NMT reporting stupid memory usage that is hard to track coz regular metrics dont expose it.
So you have to enable NMT which in most cases is a straight 5-10% performance degradation.
And for latency use ZGC or Shanondoah.
And dont forget 50 jvm flags to tweak memory usage of various parts of memory that can negatively impact your production like caches, symbol tables, metaspace, thread caches, buffer caches and other.
God I hate that so much. Just let me set one param for memory and lets be over with it.
