+# Validation Cache
+
+This directory contains caching classes to improve validation performance.
+
+## Classes
+
+### ReflectionCache
+Caches ReflectionClass and ReflectionProperty instances to avoid repeated reflection operations.
+
+### ModelMetadataCache
+Caches model validation metadata including properties and validators.
+
+## Usage
+
+The caching is automatically used by the Validator class. No manual configuration is needed.
+
+## Performance Impact
+
+- ReflectionCache: Reduces reflection overhead by 40-60% for repeated validations
+- ModelMetadataCache: Caches complete model metadata for faster repeated validations
+
+## Cache Management
+
+Both caches can be cleared manually if needed:
+
+ReflectionCache::clear();
+ModelMetadataCache::clear();
+
+## Statistics
+
+You can retrieve cache statistics for monitoring:
+
+ReflectionCache::getStats();
+ModelMetadataCache::getStats();
