Statistically Rigorous Performance Comparison
Write JavaScript functions, run them head-to-head, and get results you can trust. Benchmark Studio uses paired t-tests, confidence intervals, and baseline-corrected timing to tell you whether one implementation is genuinely faster than another — not just lucky on one run.
Features
- Side-by-side JavaScript function benchmarking with syntax-highlighted editors
- Configurable trial count, iterations per trial, and warmup runs
- Paired two-sample t-tests with configurable significance levels
- 95% confidence intervals on mean execution time
- Baseline overhead correction for accurate sub-microsecond measurement
- Suite setup code shared across all functions
- Exportable results and shareable benchmark URLs
