How would you evaluate tradeoffs between Julia's JIT and AOT compilation for production systems?

JIT improves flexibility and specialization, while AOT improves startup time and predictability.

Julia’s JIT enables runtime specialization based on actual types, yielding high performance. However, it introduces latency at first execution. AOT via sysimages removes this cost but reduces flexibility and increases build complexity. Production systems often combine both: AOT for core libraries and JIT for dynamic workloads.
