This change integrates mimalloc as the default memory allocator for Regorus, delivering significant performance improvements across all evaluation modes and language bindings. Technical Implementation: - Build mimalloc in vendored mode from C sources (following QSharp approach) - Implement GlobalAlloc trait for seamless Rust integration - Add optional 'mimalloc' feature flag for conditional compilation - Add comprehensive ACI benchmarks to measure evaluation performance Performance Impact: Rust Engine Evaluation: - Single-threaded: ~29% improvement (423 vs 328 Kelem/s) - Multi-threaded: Better scaling with reduced thread contention - Fresh engines: ~24% improvement (56 vs 45 Kelem/s) Rust Compiled Policy Evaluation: - Single-threaded: ~41% improvement (426 vs 303 Kelem/s) - Multi-threaded: Improved allocation efficiency under contention - Fresh compilation: ~26% improvement (53 vs 42 Kelem/s) C# FFI Bindings: - Engine evaluation: ~27% improvement (279 vs 219 Kelem/s) - Compiled policies: ~29% improvement (273 vs 211 Kelem/s) - Better threading characteristics through improved underlying allocation Key Benefits: - Reduced allocation-related contention in multi-threaded scenarios - More consistent performance across different thread counts - Improved memory allocation efficiency for both native Rust and FFI workloads - Better scaling characteristics for production deployments The mimalloc integration provides substantial performance gains while maintaining full compatibility with existing code through feature flags.
