`#### Key Metrics Explained
- Mean: Average execution time across all iterations
- Median (P50): Middle value, less affected by outliers than mean
- Std Dev: Measure of variation - lower is more consistent
- Min/Max: Fastest and slowest iterations
- P95/P99: 95th/99th percentile - important for worst-case scenarios
- Memory Peak: Maximum heap usage during benchmark
- Allocations: Number of memory allocations

memo.set(n, result);
return result;
}

this.pool.push(factory());
}
}
acquire(): T {
return this.pool.pop() ?? this.factory();
}
release(obj: T): void {
this.reset(obj);
this.pool.push(obj);
}
}
`Lazy Initialization
`typescript
// ❌ Before (eager)

private cache?: Map;
private getCache(): Map {
if (!this.cache) {
this.cache = new Map();
this.precomputeValues();
}
return this.cache;
}
}

📖 Benchmarking Guide
$3
#### 1. Choose Appropriate Iterations
`bash
Quick smoke test (fast feedback)
benchoptimizer benchmark --iterations 100 --warmup 10Standard benchmark (good balance)
benchoptimizer benchmark --iterations 10000 --warmup 1000Precise measurement (for critical paths)
benchoptimizer benchmark --iterations 100000 --warmup 10000
`#### 2. Use Warmup Iterations
Always include warmup iterations to allow JIT compilation and cache warming:
`typescript
const benchmarker = new Benchmarker({
iterations: 10000,
warmup: 1000, // At least 10% of iterations
});
`#### 3. Isolate Benchmarks
Avoid cross-contamination between benchmarks:
`typescript
await benchmarker.benchmark(
() => {
return calculateMA(prices, 20);
},
{
setup: () => {
// Run before each benchmark
prices = generatePrices();
},
teardown: () => {
// Clean up after each benchmark
prices = null;
},
}
);
`#### 4. Use Multiple Threads Wisely
`bash
CPU-intensive benchmarks benefit from multiple threads
benchoptimizer benchmark --threads 8I/O-bound benchmarks may not benefit
benchoptimizer benchmark --threads 1
`#### 5. Focus on Percentiles
For production systems, P95 and P99 are often more important than mean:
`typescript
if (result.stats.percentiles.p95 > SERVICE_LEVEL_OBJECTIVE) {
console.warn('Performance SLA violation!');
}
`$3
#### Pitfall 1: Not Accounting for GC
`typescript
// ❌ Bad: GC can skew results
for (let i = 0; i < iterations; i++) {
const result = new Array(1000000).fill(0);
}// ✅ Good: Reuse objects
const buffer = new Array(1000000);
for (let i = 0; i < iterations; i++) {
buffer.fill(0);
}
`#### Pitfall 2: Dead Code Elimination
`typescript
// ❌ Bad: Optimizer may eliminate unused code
function benchmark() {
calculateMA(prices, 20);
}// ✅ Good: Use the result
function benchmark() {
const ma = calculateMA(prices, 20);
return ma[ma.length - 1];
}
`#### Pitfall 3: Not Considering Variance
`typescript
// ❌ Bad: Ignoring high variance
if (result.stats.mean < baseline.mean) {
console.log('Faster!');
}// ✅ Good: Consider statistical significance
const isSignificant = result.stats.stdDev < baseline.stdDev * 0.1;
if (isSignificant && result.stats.mean < baseline.mean) {
console.log('Significantly faster!');
}

`
Running 1,000,000 iterations:
Native timing: 2.3 seconds (0.0023 μs overhead per iteration)
WASM timing: 2.8 seconds (0.0028 μs overhead per iteration)
JS baseline: 5.1 seconds (0.0051 μs overhead per iteration)Result: BenchOptimizer is 2.2x faster than pure JS implementation
