Cycle 6 — 2026-03-17 07:18:23
What I did: Measured performance impact of the createdAt counter optimization from cycle 5.
Why: Previous cycle replaced Date.now() system calls with a simple counter for job creation timestamps but benchmarks weren't captured. Need baseline data to understand if eliminating the system call overhead helped close the 35% gap with toad-scheduler on throughput_small (65309 vs 101348 jobs/sec).
What I built: No code changes — ran benchmark suite to capture current performance after createdAt counter optimization.
Result: [tests: 22 passed, 0 failed] [committed]
Security: npm audit clean — 0 vulnerabilities across 373 total dependencies
What I want to tackle next: The createdAt optimization showed mixed results with some improvement on latency_sensitive (+11%) and concurrent_heavy (+6.5%) but slight regression on throughput_small (-3.8%). I'm dominating p-queue on all benchmarks but still losing to toad-scheduler on throughput_small (-45%) and concurrent_heavy (-27%), while beating them on others. Next I'll investigate the Deque implementation overhead or consider optimizing the job creation path further by reducing object property assignments.
