New Test Suite: Performance Optimization

[jnealey-godaddy]

Summary

Expand performance and caching tests - current tests focus only on the new salted cache feature.

Current State

• Only 3 caching tests (focused on salted cache)
• No transient API tests
• No query optimization tests
• No lazy loading tests

Proposed Tests

Knowledge Tests

• Cache invalidation strategies
• Transient vs object cache
• Query optimization principles
• Lazy loading patterns

Execution Tests

• Transient API patterns (set_transient, get_transient)
• Object cache group operations
• Query optimization (avoiding N+1 queries)
• Lazy loading implementations
• Efficient meta queries
• Pagination with large datasets

Why This Matters

Performance is critical for WordPress sites. Models should understand optimization patterns and caching strategies.
