   I've made some measurement in comparison with master branch.
The patch definitely increase memory consumption up to 8%.
It doesn't affect performance significantly (2-3% difference is a typical
measurement mistake)

for phpng I just may to compare the base structure sizes, because
str_size_and_int64 has to be adopted for phpng first.

Thanks. Dmitry.
