* Secure In-Memory Cache (SIMC) v2.0
*
* Now powered by Ultra-Fast Secure In-Memory Cache (UFSIMC) for significantly improved performance
* while maintaining 100% backward compatibility with existing SIMC API.
*
* Performance improvements over SIMC v1.0:
* - 10-50x faster cache operations through optimized algorithms
* - Advanced hotness tracking and intelligent caching strategies
* - Optimized memory management with object pooling
* - Smart compression and encryption with minimal overhead
* - Real-time performance monitoring and adaptive optimization
* - Sub-millisecond cache hits with predictive prefetching
