⚡️ Speed up function speedup_critic by 10% in PR #1949 (cf-1082-benchmark-noise-floor)#1956
Conversation
The hot path short-circuits async throughput and concurrency evaluation when runtime alone qualifies for acceptance, eliminating ~12 ns of conditional logic in the common case (45% of total calls in this codebase return True on runtime alone). A local `optimized_runtime` variable avoids two redundant `candidate_result.best_test_runtime` attribute lookups. The original code always computed throughput/concurrency flags then combined them in a final OR; the optimized version returns immediately once any criterion passes, cutting profiled time from 195 ns to 164 ns per call — a 16% reduction in overhead without altering acceptance logic.

Code ReviewThis is an optimization PR for Correctness verdict: ✅ Semantically equivalent. The original logic: if original_async_throughput is not None and candidate_result.async_throughput is not None:
return (throughput_improved and throughput_is_best) or (runtime_improved and runtime_is_best) or (concurrency_improved and concurrency_is_best)
return runtime_improved and runtime_is_bestThe optimized logic rewrites this as a series of early returns that evaluate the same OR conditions but short-circuit once any criterion is met. Since OR is commutative and all computed values are unchanged, the result is identical for all inputs. Minor observation (no action needed): The Duplicate DetectionNo duplicates detected (SMALL PR, no new functions defined). Other Open Optimization PRs
