30 GB heap with a 10 ms pause budget: G1 or ZGC, and why?
Tests whether you pick ZGC -- G1's pause times scale with heap size and live-set complexity, typically landing in tens-to-hundreds of ms on a 30GB heap, while ZGC's concurrent, region-based collection keeps pauses sub-millisecond regardless of heap size, which is the only way to reliably hit a 10ms budget.
