> These GCs have a 1GB overhead when working with a 16GB heap. That’s 6% of your available memory.
6% memory overhead while preserving throughput is actually quite excellent. Just a little more than the average fragmentation overhead under manual memory management.
Manual memory management can "hold its own" because it can tailor the allocation/release profile to the problem and aggregate some of those overheads.
