Design exercise: Runtime & Performance Engineering
Profiling, allocation, JIT/AOT execution, garbage collection, scheduling, contention, and tail latency. Implement designOutline() returning non-empty values for: workload, profile, measurement. Each value must name a concrete mechanism or decision.
The mechanism
Performance work starts with a workload and a profile. Optimize the dominant resource, preserve correctness, and measure throughput, tail latency, memory, and cost together.
Expected evidence
A design outline with workload, profile, measurement plus an explicit failure mode or trade-off.

Hints when you need them
- Name the failure mode before selecting the mechanism.
