🚀 Fine-tune Benchmark.ips for Statistical Confidence

When measuring code paths in high-stakes systems, controlling warmup, sample size, and confidence intervals is crucial. Use benchmark/ips’ advanced configuration to adjust the warmup duration, measurement time, and error tolerance to get statistically significant results across runs.

require 'benchmark/ips'

Benchmark.ips do |x|
  x.config(time: 5, warmup: 2, confidence: 95, guarantee: 99)

  x.report("fast_path") do
    # optimized implementation
    FastPath.process(data)
  end

  x.report("fallback") do
    # slower fallback implementation
    Fallback.process(data)
  end

  x.compare!
