What behavior changes?
Serde JMH and live-service e2e benchmarks now report
ops_per_cpu_sec, computedfrom completed operations and process-wide CPU time. Converted JMH results fail
clearly if the metric is missing, and short e2e samples report it as unavailable.
Why is this change needed?
Add a CPU-efficiency metric alongside the existing benchmark latency and
throughput measurements.
How was this validated?
Added unit tests, ran all benchmark
checktasks and formatting, and ran JDK 25JMH smoke tests for RPC v2 CBOR and AWS JSON. Also verified the shaded JARs and
the missing-metric failure path.
What should reviewers focus on?
The process CPU-time boundaries, weighted JMH aggregation, and Gradle/Shadow
packaging of the shared profiler and generated service descriptors.
