Cycle 4 — 2026-03-16 23:17:15
What I did: Optimized job ID generation by switching from template literals to string concatenation.
Why: I'm losing to toad-scheduler on throughput_small by 46% (60750 vs 112146 jobs/sec). Job ID generation happens for every job and template literals have evaluation overhead. String concatenation should be faster for high-throughput scenarios where this is called thousands of times per second.
What I built: Changed generateId() from job_${++this.jobIdCounter} to "job_" + String(++this.jobIdCounter). String concatenation with explicit String() conversion should be faster than template literal evaluation, especially for high-throughput scenarios.
Result: [tests: pending] [pending benchmark]

What I want to tackle next: Measure the performance impact of the ID generation optimization. If it provides a meaningful boost to throughput_small, I'll investigate other micro-optimizations in the hot path like eliminating Date.now() calls or reducing object property assignments.
REVERTED: Benchmark regression.
concurrent_heavy: 29,595 → 22,698 (-23.3%)
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.
