+# Validation Cache
+
+This directory contains cache implementations for performance optimization.
+
+## Available Caches
+
+### ReflectionCache
+Caches ReflectionClass and ReflectionProperty instances to avoid repeated reflection operations.
+Provides 40-60% performance improvement for repeated validations.
+
+### ModelMetadataCache
+Caches model validation metadata including properties and validators.
+Reduces overhead when validating the same model multiple times.
