Поддерживает функции оптимизации скриптов, кэширование байт-кода в оперативную память, кэширование пользовательских данных в shared memory, простое профилирование работы скриптов. Имеет собственный GUI, наличие и использование которого, однако, не обязательно для функционирования пакета. Бесплатен. Автор всегда делал основной упор на "стабильность работы".
Поддерживает PHP4 и PHP5, включая 5.6
