Heap too small triggers G1 humongous allocations; too large balloons pause times on Graviton. Corretto on ECS/EKS/Lambda Java—when ZGC generational beats G1 for API heaps.

Project Loom virtual threads help I/O-bound Java on ECS—not CPU-bound aggregation. Compare actor models, lock-free queues, and when Lambda concurrency beats pinning threads on EC2.
