Zeev shared on twitter the result of benchmarking PHP 5.5 with Opcode cache which will be officially available for the next PHP5.5 release. The first benchmark have been run with PHP 5.5.0 development branch, compared to APC development version (Jan 28,2013), and in the second benchmark Optimizer+ have been tuned for fastest possible performance.



The performance is at its highest rate with Zend Framework test compared to APC (242.83%), but for real world applications like Drupal, Scrum, Typo3, WordPress,Xoops … the overall performance compared to APC goes between 10 and 20%. Optimizer+ according to this benchmark is amazing … for ZF!
