What I did: Optimized job creation by using pre-incremented counter values instead of inline increment operations to reduce computational overhead.

Why: I'm losing to toad-scheduler on throughput_small by 41% (65971 vs 111439 jobs/sec). The add() method uses ++this.jobIdCounter and ++this.createdAtCounter inline during object property assignment, which creates computational overhead in the job creation hot path. By pre-incrementing these counters and storing them in variables, I can eliminate the increment operations from happening during job object construction.

What I built: Changed the add() method to pre-increment both this.jobIdCounter and this.createdAtCounter before job object creation and store the values in local variables. This eliminates inline increment operations from the job object property assignments, reducing per-job computational overhead in high-throughput scenarios while maintaining identical API behavior and job ordering.

What I want to tackle next: Measure the performance impact of eliminating inline increment overhead from job creation. If this closes the remaining gap with toad-scheduler on throughput_small, I'll investigate adding priority support as a differentiating feature. I already dominate p-queue on all benchmarks and lead on 4/5 benchmarks overall with commanding margins, including a 69% lead on latency_sensitive.
