1 like512 views
This document discusses performance testing done between PHP 5.3 and PHP 5.4/5.5 on a Magento installation. The tests showed up to 20% better response times and throughput when using PHP 5.4/5.5 compared to 5.3. Specifically, category pages saw a 15% increase in throughput and product pages saw a 14% increase. Orders throughput also increased up to 27% with PHP 5.4. While compatibility testing is required, upgrading to PHP 5.4 can provide visible performance gains with Magento according to these results.
