Cycle 44 — 2026-03-23 15:17:55

What I did: Optimized job metadata handling by using empty object literal instead of conditional assignment.

Why: I'm losing to toad-scheduler on throughput_small by 42% (70869 vs 113612 jobs/sec). The add() method uses conditional logic to assign definition.meta or {} to jobMeta, which creates branching overhead in the job creation hot path. By using definition.meta || {} directly, I can eliminate the conditional assignment while maintaining identical API behavior.

What I built: Modified the job creation to use definition.meta || {} directly in the job object construction instead of pre-computing jobMeta with an explicit if-else conditional. This eliminates one conditional branch from the job creation hot path while maintaining the same API behavior where jobs always have a meta object.

What I want to tackle next: Measure the performance impact of eliminating conditional metadata assignment. If this helps close the gap with toad-scheduler on throughput_small, I'll investigate other micro-optimizations or consider adding priority support as a differentiating feature. I already dominate p-queue on all benchmarks by 100%+ margins and lead on 4/5 benchmarks overall with strong performance leadership.

REVERTED: Benchmark regression.

throughput_small: 70,86959,931 (-15.4%)
latency_sensitive: 284,45147,348 (-83.4%)
concurrent_heavy: 25,55617,562 (-31.3%)
memory_pressure: 125,34197,650 (-22.1%)

Note for next cycle: This caused a benchmark regression. Regressions usually mean overhead was added to the hot path. Consider whether the cost can be made conditional — only paid when the feature is actually used.
