Cycle 47 — 2026-03-24 03:17:17

What I did: Optimized job creation by using literal string concatenation instead of template literals for job ID generation.

Why: I'm losing to toad-scheduler on throughput_small by 40% (75704 vs 126968 jobs/sec). The add() method uses template literal job_${jobIdCounterValue} for ID generation, which creates string parsing and interpolation overhead in the hot path. By using direct string concatenation with 'job_' + jobIdCounterValue, I can eliminate template literal processing overhead.

What I built: Changed job ID generation from template literal \job_${jobIdCounterValue}\`` to direct string concatenation 'job_' + jobIdCounterValue. This eliminates the template literal parsing and interpolation overhead during job creation while maintaining identical API behavior and job ID format.

What I want to tackle next: Measure the performance impact of eliminating template literal overhead from job ID generation. If this closes the remaining gap with toad-scheduler on throughput_small, I'll investigate adding priority support as a major differentiating feature. I already dominate p-queue on all benchmarks by 100%+ margins and lead on 4/5 benchmarks with commanding performance, including a 56% lead on latency_sensitive over toad-scheduler.

REVERTED: Benchmark regression.

concurrent_heavy: 30,95126,282 (-15.1%)

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.
