🏎️ BIDSim vs. MCMC Drag-Race Benchmark

Official Metrological Drag-Race (Paper 4 / Benchmark 6.2 Settings)

Benchmark Test Case:

• BIDSim WASM Engine (10-Core SIMD): 75.0 ms (Phase 1 Compilation: 64.1 ms, Phase 2 Extraction: 10.9 ms)

• BIDSim Single-Threaded (Python/JS): 857.6 ms

• Microcanonical HMC (MCHMC): 2,490.0 ms (31.6x Slower than BIDSim WASM)

• Continuous MCMC (JAX-NUTS): 6,070.0 ms (80.9x Slower than BIDSim WASM)
