PHPNG is a new branch of PHP development. It aims to bring better memory usage efficiency and performance. PHPNG is focused on PHP’s VM Zend Engine. PHPNG aims to provide the maximum performance for current applications by rebuilding internal structures of PHP. Existing structure leads to the next time expenditures: 20% of time are used for tasks of memory manager, 10% – for hash tables, 30% – for call internal functions and only 30% – for execution in virtual machine. PHPNG can do a 10-30% execution speed improvement by changing this structure. Also it leads to some memory savings.
