|
* Performance Benchmark Suite for T023 Final Optimization Validation
|
|
*
|
|
* Comprehensive benchmarking framework to validate performance improvements:
|
|
* - API operation benchmarks (connection pooling, caching, batching)
|
|
* - Database operation benchmarks (batch operations, prepared statements)
|
|
* - Memory usage benchmarks (streaming, object pooling, garbage collection)
|
|
* - Autoloader optimization benchmarks (class preloading, caching)
|
|
* - Before/after comparison analysis
|
|
* - Performance regression testing
|
|
*
|
|
* Target: Validate 5%+ performance improvement beyond PHP 8.4 baseline
