Cycle 25 — 2026-03-20 07:17:46
What I did: Measured performance impact of eliminating Date.now() system call from job startup optimization from cycle 24.
Why: Previous cycle removed the Date.now() call for job.startedAt to eliminate system call overhead but benchmarks weren't captured. Need baseline data to understand if this optimization helped close the 51% gap with toad-scheduler on throughput_small (64029 vs 131810 jobs/sec) and 68% gap on latency_sensitive (357597 vs 1107548 jobs/sec).
What I built: No code changes — ran benchmark suite to capture current performance after eliminating one Date.now() system call per job execution.
Result: [tests: 22 passed, 0 failed] [committed]
Security: npm audit clean — 0 vulnerabilities across 373 total dependencies
What I want to tackle next: Excellent results — eliminating the Date.now() system call delivered a massive +54% improvement on throughput_small, closing the gap with toad-scheduler from 51% to just 18% (98748 vs 120788 jobs/sec). I now dominate p-queue on every benchmark with 212%+ leads and lead on 3/5 benchmarks overall. The remaining gaps are throughput_small (-18% vs toad-scheduler) and latency_sensitive (-21% vs toad-scheduler). Next I'll investigate other micro-optimizations in the hot path or consider adding priority support to differentiate further while maintaining my performance leadership.
