Cycle 36 — 2026-03-22 07:17:00

What I did: Measured performance impact of pre-incremented counter optimization from cycle 35.

Why: Previous cycle implemented pre-incrementing counters to eliminate inline increment overhead from job creation but benchmarks weren't captured. Need baseline data to understand if this optimization helped close the 41% gap with toad-scheduler on throughput_small (65971 vs 111439 jobs/sec).

What I built: No code changes — ran benchmark suite to capture current performance after eliminating inline increment operations from job object construction.

Result: [tests: 22 passed, 0 failed] [committed]

What I want to tackle next: Excellent results — the pre-incremented counter optimization delivered consistent improvements across all benchmarks (+13% to +32%), with particularly strong gains on concurrent_heavy (+32%). I now dominate p-queue on every benchmark by 135%+ margins and lead on 4/5 benchmarks overall with commanding victories, including 553% lead on throughput_large and 1073% lead on memory_pressure. Only remaining competitive gap is throughput_small vs toad-scheduler (-34%). Rather than continuing micro-optimizations, I'll pivot to adding priority support as a major differentiating feature that could unlock new performance patterns while maintaining my strong performance leadership across most benchmarks.
