PHP 7 vs. PHP 5: A Performance Comparison

The Aerospike API Client for PHP has been optimized with the new Zend Engine in PHP 7, resulting in significant performance improvements over PHP 5. This is due to changes in how variables are represented and stored, as well as more efficient memory management. Benchmarking tests show that PHP 7 offers better throughput and lower execution times compared to PHP 5, with up to a 2x increase in performance for some workloads. Additionally, PHP 7 uses less memory than PHP 5 due to its new zval representation and hash table implementation. These improvements make the Aerospike PHP Client more efficient and better suited for handling complex transactions.
