Using ecalloc() to create objects is expensive, because the dynamic-size memset() is unreasonably slow. Make sure we only zero the main object structure with known size, as the properties are intialized separately anyway. Technically we do not need to zero the embedded zend_object structure either, but as long as the memset argument is constant, a couple more bytes don't really matter.
