//! Performance test suite for nonce-auth storage backends
//!
//! This module contains comprehensive performance tests for all storage backends
//! to ensure optimizations provide expected improvements and meet performance targets.
//!
//! ## Running Performance Tests
//!
//! Run all performance tests:
//! ```bash
//! cargo test --test performance
//! ```
//!
//! Run specific backend tests:
//! ```bash
//! cargo test --test performance memory
//! cargo test --test performance --features sqlite-storage sqlite
//! cargo test --test performance --features redis-storage redis
//! ```
//!
//! Run with all features:
//! ```bash
//! cargo test --test performance --all-features
//! ```
