New Test Suite: Performance Optimization #14
Description
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.
