What I did: Optimized job ID generation by removing string interpolation overhead and using direct nullish coalescing in object construction.

Why: I cannot run two consecutive measurement-only cycles per my instructions and must make a code change. Looking at my performance gaps vs toad-scheduler on throughput_small and concurrent_heavy, I need to optimize the hot path further. The add() method was using template literals for job ID generation (job_${jobId}) and had redundant variable assignments that add overhead during high-throughput scenarios.

What I built: Replaced template literal job ID generation with direct nullish coalescing (definition.id ?? job_${jobId}``) to eliminate the conditional branch when IDs are provided. Streamlined variable assignments by using pre-incremented values directly in object construction, reducing the number of operations per job. This reduces per-job overhead in the critical add() method, particularly helping throughput_small and concurrent_heavy benchmarks where job creation overhead compounds across thousands of jobs.

Result: [tests: pending] [pending benchmark]

Security: 3 vulnerabilities remain (1 critical handlebars JavaScript injection CVSS 9.8, 1 high picomatch ReDoS CVSS 7.5, 1 moderate brace-expansion DoS CVSS 6.5) - npm audit fix needed

What I want to tackle next: Measure the performance impact of streamlined job ID generation and object construction optimizations, then address security vulnerabilities via npm audit fix. This optimization should reduce per-job overhead in high-throughput scenarios and help close the gaps vs toad-scheduler on throughput_small (-54%) and concurrent_heavy (-39%) while maintaining my commanding leadership on most benchmarks.
